Many people today don't have th understanding that repair is an Art and not simply a clean and simple process that many are today. The word for Today is " Innovative" What the repair of tape decks is just as good as using one. Im 53 and still impressed with the cassette tapes as well as the players. It truly is one of the living arts. Good Video 😎
You can buy any cheap Technics double deck from mid 90s. They are all bricked because a plastic gear but their motors are PERFECT. They are double speed, but with an external potentiometer you can set any speed you want. I guy asked me on boomboxery that he was having trouble with motors, and told him just to buy a parts deck. He grabbed a technics for only 7 pounds instead of paying 10 times more to thieves for just the motor itself. An this mid 90s motors were IMHO the finest ones in term of "perfection" (due to decades of experience). Very stable.
Yes this is what i normally do. I pick up cheap tape decks for about 10 and strip them for parts. Just the second hand shop has been closed for months due to covid.
I have one of these. In Europe, it was sold as the CT-S820S. The AutoCal with manual bias fine adjustment is the best-working that I have ever encountered and the mechanism is amazingly smooth and silent. Its frequency response can go up to 28 kHz at +/- 3dB on a Type IV tape - I measured it myself, it's unbelievable. Unfortunately, my unit's Dolby S circuitry shows severe mistracking on the right channel in the low frequency range between 50 and 500Hz which makes it unusable for me. It also seems to have a grounding issue because on some settings, there seems to be an inaudible noise that overloads the level meters and goes away as soon as I touch the front shielding plate where the head cables plug into the main board. I'll probably have to recap the Dolby boards and add in some trimmers so these freakin' things can be adjusted on their playback level - something that Pioneer somehow refused to add to the design. The Kenwood KX-9050S (I also have one of these beauties) allows to adjust playback levels between Dolby Off/Dolby S iteratively, at least. Also, adjusting head azimuth is a real pain on its slanted mechanism, as well as cleaning because it sits so freakin' deep inside the deck. Also, I cannot for the love of god understand why Pioneer gave this deck such crude level meters. Even with the meter spreading, it isn't very useable to properly level a recording.
Wish I could have seen more of the disassembly procedure, either the two hands were obscuring what the tool was doing, or the camera was pointed at another place and the detailed view of that operation were performed off camera. Beyond that, the problem analysis and repair was great to watch!!
Welcome to the new Assistant! they are usually very vocal.Sort of thing id do and reminds me of when I swapped the armature out of a lawn mower as my electric-drill packed up. ok, it commutated slower, but it got me by. Necessity being the mother of....
At the age of 49 it was discovered that I had cancer in my jaw from what I thought was an abscess tooth. After having had the cancer removed, reconstruction surgery, and chemo and radiation, at the age of 60 I’m still cancer free. God gets all the glory along with my family and friends. I’ve been back to work since August 2010. I left work for the surgeries in December 2009.
I fixed the motor in my Nakamichi 1000 and that was very difficult because of the intricate mechanical construction of the power connectors but it was very educational (patience) and rewarding. Great job!
To be honest I appreciate your workaround fixes and have learned from the technology behind them. Transplanting a motor from a dual cassette deck is no worse than putting two resistors in series to achieve a required value. Some people obsess too much over 'originality'. Put simply, you can have a working cassette deck or an ornament. My 2c ;)
It's a great machine! As TAS said about its bigger, and even "badder" brother, the CT-93: (Paraphrased) "Pioneer perfected the cassette format just in time for the format's fall from widespread use, but it still provides access to pure analog sources of music". I have both, along with a couple of Dragons, an RX-505, a DR-1, and a BX-300. (Along with four of the Pioneer's venerable ancestor, the CT-F1250 and two CT-F1000's.) The Dolby S on the 93, 43 (and 95, although I don't own a 95, it's an even closer relation to this design than the 93) can, when making new recordings on good tape, put an analog cassette on par with the best digital. I'm changing the CT-43 door motor belt and this video was very helpful! Thanks for uploading this!
I like your new assistant! That solution with the motor was the best one. NOS cult and audiofoolery is definetively not science. If you don't use low oxygen cooper it 'sounds bad'. C'mon!
Hey there Dave.... as far as I remember these motors have a variable resistor built in the motor assembly. When you look at it from the back the of centre hole is the variable resistor that you can adjust.... btw great videos you do... watch them all the time... keep it up
There are different versions from different manufacturers. Some has no internal pot at all. Some has an internal pot for normal speed, and an A and B terminal for the high speed, which if you short, it goes full speed, or if you add an external pot, you can adjust the high speed, too. In some tape decks, the high speed was used just to make FF and REW faster, so they don't need any adjustment to that, the faster the better. Some had high speed dubbing (eew...), and they needed the speed control for the high speed, because the two decks must run at identical speed during high speed dubbing.
Yes, this an issue these days getting parts for Cassette decks, but there is hope I am working on a project to provide upgrade kits for the Pioneer CT F500, as there is so many about today. This will be in a form of a replacement built up circuit board, that can be install, that will provide new technology to a very old format. I am still testing parts of the circuit and making the required changers, it is not easy to do the software / electronics from the ground up. The good news is, it uses easy to get parts and the plan is to have it as kit set available next year some time, base on what time I have got to work on this project.
There are NOS Mabuchi and Sankyo 12V CCW 2400RPM tape deck motors on Aliexpress, and they are genuine, Both the internal and external pot version. I have bought about 10 of them in this year. I can send you links to the sellers in email if you are interested. The motors are in various conditions, most of them are perfect, some has some spots of corrosion, and I got one that arrived with a frozen shaft (although externally it wasn't badly corroded). All need to be disassembled for lubrication, as they are 25-30 years old. Two arrived with the terminal tab broken off of the PCB. They were in an envelope instead of a box. I complained to the seller with photos, she was ready to send replacements, but I suggested her not to send replacements separately, just add two extra motors for my next order. My next order happened about 2 or 3 months later, I asked for the two extra motors in the 'notes for the seller' field according to our agreement, and they added the 2 free motors, packed them very well in a box. Although one of those was the frozen one, I haven't complained that time, they are so cheap, and that one is probably repairable. Or if not, I can swap the board from it into one of the broken tab ones. It seems like their Mabuchis are better than their Sankyos. In the Sankyos, the brushes are just those thin phosphor-bronze sheet fingers, in the Mabuchis, it seems like they have an extra piece of (possibly silver alloy) contact material spot welded onto the bronze fingers where they come in contact with the commutator.
A good fix! It makes it quite clear you have to reuse materials for restoring old tape decks. i was just wondering about a detail. All that tape decks are advertised als super accurate and then you can replace such motor by a standard motor. And be aware, this is a Dolby S tape deck.
Seems like a perfectly suitable drop-in replacement to me. :) If we really wanted to get silly, cut a hole in the back for a standard pot with center detent in series with the cal pot inside to add a pitch control function. I'm slightly annoyed that they didn't use a quartz-locked direct drive motor in an apparently expensive dual-capstan machine, but then a lot of other people didn't either. At least the flywheels in that one are lumpy enough for a standard-issue capstan motor to meet the W&F spec that they wanted.
Your cassette deck repair vid's are spiffing as always!! - You could have asked your lovely cat for help changing the belts but she would probably have said - "Mee Owww?"
If it came broken and you fixed it by any means necessary, then I’m sure the man or woman who you fix this for is well please ....since you can’t get these machines again. good job
Excellent repair dave , there is nothing wrong with the way you fixed it. The motor will likely outlast the rest of the deck. I looked for motors a few weeks back, eather cheap muc-pukie or unused old ones sold by Pacific stereo with there label on the motor so you don't know the original brand. (not cheap). The old motors with the pass transistor nailed to the case. Beautifull cat, stunning eyes.
Fantastic job with what parts you could find sometimes people forget you can always find the right part to the right job so you going to do with what you could find
The LA5531 is still available as cheap NOS part (at least on eBay Germany), in such a case I always try to repair the motor first and would replace the IC. Less effort than searching for a complete motor in my opinion.
@@12voltvids Yes, the brushes seem worn out completely (and severed) at the contact point, they look way too short, barely reaching the commutator.. At that point, it was just a matter of time until they either shorted through the same commutator pad or one of them was dragged to the other side (catching in the commutator separation gaps), directly touching the other. Just one observation: when connecting a trimmer pot as a variable resistor it's always good practice to connect the vacant extremity to the cursor. It can be life saving if the cursor stops touching the track. Although here, infinite resistance seems reasonably safe.
I wouldn't care what one would say..., it still good fix even it's robbing Peter to pay Paul!! Plus you gave a new lease on life for another tape deck!
There is nothing wrong with substituting original parts, I've done it many times! Just one more thing, shipping costs seem to be very expensive across the pond, I'm in the UK.
Just the best way to handle that cassette deck! Well done again, no hacking there, because I don't know if anyone could have that specific motor, and sourcing a NOS Japanese one is fantastic, something you normally pay a lot, done with an abandoned inherited ghetto blaster! You could have dozens of these motors, and absolutely none fitting or with the proper voltage, you had the kind of chance few have in service stations nowadays, most would have say can't be found, unavailable... Or at least ask for a similar machine to get parts. So with a Pioneer, that's not as easy as for very sought after brands or CD players, I would say fantastic, your customer is fairly lucky! Some would assume it's a curse from your new siamese assistant, maybe it's interest for this particular job was a sign of the gods? Anyway, I think he has adopted a good hooman, these cats have also Elite taste for that...
Nice job,on tapeheads there is a guy called pacific stereo who sells universal capstan motors,may be useful in case you would need it for another repair.
I like how the motor can b removed easily from the cassette mechanism,,,,without undoing the screws in place,,,,like quick turn to lock into place. And the cassette door,,,open and close,,,wish I had a cassette deck with that motorised eject cassette door.
Good fix. Something I do after I work on something, especially if I make a mod like that, is write up a short description on a card and tape it to the inside of the case to let the next guy know what I did and what the mod is about. Sometimes the next guy is me, and it's a good reminder.
I did write on chassis speed control pointing at the control. Don't need to be a rocket scientist to figure this out. the leads from the control go directly to the two terminals on the motor tag l&h
It's impossible to find those capstan motors in single quantities, and original from Japan are NLA. The deck works. Maybe, I would just solder the pot and resistor closer to the motor.
What a hack job, but a brilliant repair. i have had to botch repair before not long after some Japanese made models just stopped making parts! Production run stops, spares stop! I just said "What a hack job" because you said people would say that ha ha ha. That was a lucky find that motor and I would have done the speed control the same way. One deck I had (not branded but a supermarket named machine) had a ten turn pot for a speed control. It was on the other side of the board, I wasn't looking for a ten turn control, I was just looking for a 1 cent skeleton pot. This deck never sounded right, but after I adjusted it it was very good for a ghetto blaster, very hard on the batteries though. Two hours, change the 10 batteries!!! Big batteries "D" cells.
@@12voltvids Yeah, it is the same here. Problem is they will not sell you a deck or anything else these days unless it works and passed electrical tests! Not even when you say you just want them for spares. Just in case you take them to court. What is this world coming to?
@@BoB4jjjjs not that has here. Used electronics can be bought and sold no problem. There was a time when people would buy cars that have been totaled from an auction and take different cars and put them together and then re-licens them and sell them to someone as a rebuilt car and that practice went on for years they just finally shut that down now if you try to do that you have to have the car recertified and not stopped that but for years there was companies rebuilding cars from Rex and putting them back on the road
@@12voltvids Got that here to, just stopped you buying right offs for repair. It can still be done but it is not straight forward! Could buy electrical stuff from auctions, still can but not many around these days. 30 miles away is nearest, doesn't sound much, but on these roads takes 1 1/2 to 2 hours depending on traffic. One is quicker, but very busy auction and everyone pays over the odds. There used to be one close, in fact two, but both died and they stopped. Even the second hand market for bits has dried up. It hacks me off as you can't get bits for older stuff I want to fix, so I gave it up. np point. CB stuff can't be got for love nor money these day either, not that it was easy when they were popular anyway. TVs are just not worth the bother these days, get a black thing with a lot of legs, fit it and bang! 20 quid lost, I stopped when they started putting a lot of ICs in them, not worth the bother. Then of course shifting house a few times people don't know where you have gone so I don't get pestered so often to fix things. Nice in a way, but sometimes you need a push to do something in a workshop. I have a 10 amp power supply that I need to fix, but because it is mine I can't be bothered to clear out the workshop and fix it. I was studding for Radio Exam, but again, I started to do various jobs and never got back to that either. There is just not enough hours in the day. I need around 60 hours to do 12 hours of work as being disabled is a huge hinder to me. It was fine when I was fit and could walk up a mountain in an evening and go back over it to get to the car, sometimes it was very dark by the time I got back, but after a day at work it was nice to get away from people. Still had paperwork to do when I got home and then work early next day. No wonder I am burned out!
@@BoB4jjjjs And that is why I cut myself down to a 4 day work week. Still work the same hours, just 10 hour days now instead of 8, but having 3 days off every week is so nice. Everyone should be working this way.
I love the mail in repairs, i get them all the time and yes no description of the fault so its a guessing game and then sometimes theres no details of who sent it....a few months later i get calls abusing me of why i havent done it or rang the owner.....then i say...well kinda hard when you dont supply your phone number or your name....that helps you know...!!
LOL ya no kidding Today I received a big box with 4 cameras in it. Had to search my old Emails and then I found one from a viewer that said he was going to donate some old cameras for me to tear down. Don't know if I will get any working, but for sure I will dear em down and pick usable parts form them.
One possibility is to take the wires for the commutator on the old motor, and hook them directly to the power in pins and reassemble. You can then test to make sure the motor works, and use a small DC motor speed controller external to it; there’s loads of empty space in there. Hell, you could probably wire up a CMOS 555, a few resistors (and a pot), capacitors, and a TIP120 NPN driver transistor as a cheap PWM motor speed controller for a few bucks and change! 😎
12voltvids - because I thought the whole point was that motors for those were hard to come by; someone else might not have a spare cassette player they can yank a motor out of. Besides, you had the motor open, might as well try; it didn’t look like the motor windings or commutator were bad. And it’s probably easier than replacing that IC that popped! 😀
@@williamsquires3070 motors are hard to come by these days, and if you were just fixing your own unit and it it burns out after a few hours play no big deal but when it it a client's unit that is a different situation. Especially when the client is paying about 200 in shipping to get it here and back. A new or used but good shape part is really the only option. These motors are available. I found a couple of them online but by the time they get here with the shipping they cost of the motor is more than i am charging for the repair. I found a suposidly new one for sale for 45.00 plus an extra 30 shipping then there will undoubtedly be broker fees added by DHL as it was coming from Japan.
12voltvids - of course, the problem is you could still get taken for a ride even if you can find one to buy; it could be a refurb/reman, or even a Chinese counterfeit, or the mounting holes aren’t lined up correctly, or it spins the wrong way. At least with the existing motor, you know it was the right one for the application, and it fit; it just needs a little TLC, maybe a bit of light oil for the bearings, clean the commutator bars (gently, please!), and it’ll be ready for years more service. Furthermore, I’ll bet this unit had been “serviced”, and I’ll bet someone hooked up the motor the wrong way, which popped the IC. By bypassing it, even if you hook the motor up the wrong way, the worse that’ll happen is that’ll spin the wrong way; easy enough fix. Even for a Siamese cat. Okay, joking there; I don’t think your feline companion has much interest in motor servicing. 😊
Why not trying to replace the dead motor control chip? A hole might be overcurrent or overvoltage, but also just age, so the rest could still be fine. Is there a dead reverse protection diode inside the motor?
I suspect there's a short circuit somewhere in the motor itself, maybe the bushes or commutator are worn, that blew the chip with over-current. But that could be proved by powering the motor directly without the speed regulator.
Because i don't know what causes the chip to fail. Could be a shored coil. Don't need to get married to an old tape deck. Change the moter and it is done.
need suggestions on troubleshooting short circuit (possibly in PCB) in JVC CA-S50, after connecting CD/tape deck component to main tuner amp component while power was turned on...
Dave I don't know who would have a problem with how you fixed this cassette deck. However anyone that does take up any issue with the repair most likely doesn't have the ability or the knowledge to do anything that you did.
Some people have an issue just coping with life. Was on a job today and another working doing some work at the same location had a full breakdown, started crying, walked off the job and quit because the property owner asked them to put on a mask before entering the premise. I just stood there and shook my head in disbelief.
It’s a fantastic repair work. Just wondering in case you couldn’t find a suitable salvage motor what are the chances of finding the motor regulator ic and getting the original motor working again?
So... You would rather have a worn out motor with a new chip as opposed to a new motor? And yes i know sometimes you have to do this, but when a replacement motor is available that is the best option.
(@40:43) - near the top right, there appears to be some brownish glue near the regulators and a big cap; I hope that’s not that nasty stuff that becomes corrosive. 🤬
Many people today don't have th understanding that repair is an Art and not simply a clean and simple process that many are today.

I think you did a fantastic job. Without your knowledge and part, the deck would be going to the junkyard. Well done Dave.
That's right. Without a motor it is just a fancy VU meter.

I suspect that the brushes shorted and blew the IC.
@@12voltvids Yes, the brushes seem worn out completely (and severed) at the contact point, they look way too short, barely reaching the commutator.. At that point, it was just a matter of time until they either shorted through the same commutator pad or one of them was dragged to the other side (catching in the commutator separation gaps), directly touching the other. Just one observation: when connecting a trimmer pot as a variable resistor it's always good practice to connect the vacant extremity to the cursor. It can be life saving if the cursor stops touching the track. Although here, infinite resistance seems reasonably safe.
@@mihaischitcu1917 Infinite resistance and motor goes to full speed.
I wouldn't care what one would say..., it still good fix even it's robbing Peter to pay Paul!!
Plus you gave a new lease on life for another tape deck!
Gotta do what you gotta do right.
I love my old 80's 90's cassette decks. I just wanna get one with dolby S
I looked on Ebay and they have the Pioneer CT-43 Service Manual dated 1993
Great repair. Vintage electronics need to carry Donor cards! Never knew those motors had control boards. A lot of circuit board in the unit?
There is nothing wrong with substituting original parts, I've done it many times! Just one more thing, shipping costs seem to be very expensive across the pond, I'm in the UK.
very sweet cat, she reminds me of my second siamese
Boombox's sacrification saves the day!
Just the best way to handle that cassette deck! Well done again, no hacking there, because I don't know if anyone could have that specific motor, and sourcing a NOS Japanese one is fantastic, something you normally pay a lot, done with an abandoned inherited ghetto blaster! You could have dozens of these motors, and absolutely none fitting or with the proper voltage, you had the kind of chance few have in service stations nowadays, most would have say can't be found, unavailable... Or at least ask for a similar machine to get parts. So with a Pioneer, that's not as easy as for very sought after brands or CD players, I would say fantastic, your customer is fairly lucky!
Some would assume it's a curse from your new siamese assistant, maybe it's interest for this particular job was a sign of the gods? Anyway, I think he has adopted a good hooman, these cats have also Elite taste for that...
Nice job,on tapeheads there is a guy called pacific stereo who sells universal capstan motors,may be useful in case you would need it for another repair.
Love your work incredible information thank you . I am working on a Onkyo CX-70 VERY RUFF
Well done, you saved a Pioneer Elite. Thanks.
Beautiful cat!
that boombox looks nice i wonder how the sound is on it
We will find out soon. At least for the radio and cd.
Chordless tools. Greatest invention since the pocket on a shirt!!!!!
The speed is not constant. It seems to be accelerating as it plays. But at least you save the Pioneer Elite series from the bin.
Not quite what I would call a hack job because you weren't cutting corners, but it certainly was a bodge job.
I like how the motor can b removed easily from the cassette mechanism,,,,without undoing the screws in place,,,,like quick turn to lock into place.
And the cassette door,,,open and close,,,wish I had a cassette deck with that motorised eject cassette door.
Good fix. Something I do after I work on something, especially if I make a mod like that, is write up a short description on a card and tape it to the inside of the case to let the next guy know what I did and what the mod is about. Sometimes the next guy is me, and it's a good reminder.
I did write on chassis speed control pointing at the control. Don't need to be a rocket scientist to figure this out. the leads from the control go directly to the two terminals on the motor tag l&h
@@12voltvids No criticism, just saying something I do. Not every mod is obvious.
@@josephcote6120
And that is why it is noted inside the unit.
Well done! This made me happy!
"wouldn't that be a kick in the nads, even though this ain't a NAD" lol
It's impossible to find those capstan motors in single quantities, and original from Japan are NLA. The deck works. Maybe, I would just solder the pot and resistor closer to the motor.
What a hack job, but a brilliant repair. i have had to botch repair before not long after some Japanese made models just stopped making parts! Production run stops, spares stop! I just said "What a hack job" because you said people would say that ha ha ha.
That was a lucky find that motor and I would have done the speed control the same way. One deck I had (not branded but a supermarket named machine) had a ten turn pot for a speed control. It was on the other side of the board, I wasn't looking for a ten turn control, I was just looking for a 1 cent skeleton pot. This deck never sounded right, but after I adjusted it it was very good for a ghetto blaster, very hard on the batteries though. Two hours, change the 10 batteries!!! Big batteries "D" cells.
I usually hit the 2nd hand store and buy tape decks for 10.00 just to have for parts. Problem is doe to covid these stores are closed.
@@12voltvids Yeah, it is the same here. Problem is they will not sell you a deck or anything else these days unless it works and passed electrical tests! Not even when you say you just want them for spares. Just in case you take them to court. What is this world coming to?
@@BoB4jjjjs not that has here. Used electronics can be bought and sold no problem.
There was a time when people would buy cars that have been totaled from an auction and take different cars and put them together and then re-licens them and sell them to someone as a rebuilt car and that practice went on for years they just finally shut that down now if you try to do that you have to have the car recertified and not stopped that but for years there was companies rebuilding cars from Rex and putting them back on the road
@@12voltvids Got that here to, just stopped you buying right offs for repair. It can still be done but it is not straight forward! Could buy electrical stuff from auctions, still can but not many around these days. 30 miles away is nearest, doesn't sound much, but on these roads takes 1 1/2 to 2 hours depending on traffic. One is quicker, but very busy auction and everyone pays over the odds. There used to be one close, in fact two, but both died and they stopped. Even the second hand market for bits has dried up.
It hacks me off as you can't get bits for older stuff I want to fix, so I gave it up. np point. CB stuff can't be got for love nor money these day either, not that it was easy when they were popular anyway. TVs are just not worth the bother these days, get a black thing with a lot of legs, fit it and bang! 20 quid lost, I stopped when they started putting a lot of ICs in them, not worth the bother. Then of course shifting house a few times people don't know where you have gone so I don't get pestered so often to fix things. Nice in a way, but sometimes you need a push to do something in a workshop.
I have a 10 amp power supply that I need to fix, but because it is mine I can't be bothered to clear out the workshop and fix it. I was studding for Radio Exam, but again, I started to do various jobs and never got back to that either. There is just not enough hours in the day. I need around 60 hours to do 12 hours of work as being disabled is a huge hinder to me.
It was fine when I was fit and could walk up a mountain in an evening and go back over it to get to the car, sometimes it was very dark by the time I got back, but after a day at work it was nice to get away from people. Still had paperwork to do when I got home and then work early next day.
No wonder I am burned out!
@@BoB4jjjjs
And that is why I cut myself down to a 4 day work week. Still work the same hours, just 10 hour days now instead of 8, but having 3 days off every week is so nice. Everyone should be working this way.
I love the mail in repairs, i get them all the time and yes no description of the fault so its a guessing game and then sometimes theres no details of who sent it....a few months later i get calls abusing me of why i havent done it or rang the owner.....then i say...well kinda hard when you dont supply your phone number or your name....that helps you know...!!
LOL ya no kidding Today I received a big box with 4 cameras in it. Had to search my old Emails and then I found one from a viewer that said he was going to donate some old cameras for me to tear down. Don't know if I will get any working, but for sure I will dear em down and pick usable parts form them.
I thought repair center only uses manufacturers replacement
The motor you have installed is way much better in quality than the default Sankyo motor the machine has installed in.
It works, good job !
Now your chair belongs to your kitty lol.
1:57 which cat is that
i loved it
One possibility is to take the wires for the commutator on the old motor, and hook them directly to the power in pins and reassemble. You can then test to make sure the motor works, and use a small DC motor speed controller external to it; there’s loads of empty space in there. Hell, you could probably wire up a CMOS 555, a few resistors (and a pot), capacitors, and a TIP120 NPN driver transistor as a cheap PWM motor speed controller for a few bucks and change! 😎
Why go to hat trouble, Just change the motor.
12voltvids - because I thought the whole point was that motors for those were hard to come by; someone else might not have a spare cassette player they can yank a motor out of. Besides, you had the motor open, might as well try; it didn’t look like the motor windings or commutator were bad. And it’s probably easier than replacing that IC that popped! 😀
@@williamsquires3070 motors are hard to come by these days, and if you were just fixing your own unit and it it burns out after a few hours play no big deal but when it it a client's unit that is a different situation. Especially when the client is paying about 200 in shipping to get it here and back. A new or used but good shape part is really the only option. These motors are available. I found a couple of them online but by the time they get here with the shipping they cost of the motor is more than i am charging for the repair. I found a suposidly new one for sale for 45.00 plus an extra 30 shipping then there will undoubtedly be broker fees added by DHL as it was coming from Japan.
12voltvids - of course, the problem is you could still get taken for a ride even if you can find one to buy; it could be a refurb/reman, or even a Chinese counterfeit, or the mounting holes aren’t lined up correctly, or it spins the wrong way. At least with the existing motor, you know it was the right one for the application, and it fit; it just needs a little TLC, maybe a bit of light oil for the bearings, clean the commutator bars (gently, please!), and it’ll be ready for years more service. Furthermore, I’ll bet this unit had been “serviced”, and I’ll bet someone hooked up the motor the wrong way, which popped the IC. By bypassing it, even if you hook the motor up the wrong way, the worse that’ll happen is that’ll spin the wrong way; easy enough fix. Even for a Siamese cat. Okay, joking there; I don’t think your feline companion has much interest in motor servicing. 😊
@@williamsquires3070 Last resort. For a pair repair a new motor is in order.
Hi Dave What Hitachi Trk unit was it that you have with missing parts might be able to help, by the way fantastic work, UK England
Hello ,
I, know where, to look, in your local, junk yard for your, project they have a mess of them!!
Super robota. POLAND
If you also saw the repairman's cat, like this video xd lool
While I appreciate your repair, at first blush setting the speed of this motor in this fashion with a resistor be temperature dependent?
The motor normally just has this same control inside the motor.
It is a very good job indeed very impressive
GREAT JOB hey if the part fits at this point and it works ...its fixed...parts hard 2 find
Great work. Nice solution. Big thumbs up.👍
Why not trying to replace the dead motor control chip? A hole might be overcurrent or overvoltage, but also just age, so the rest could still be fine. Is there a dead reverse protection diode inside the motor?
I suspect there's a short circuit somewhere in the motor itself, maybe the bushes or commutator are worn, that blew the chip with over-current. But that could be proved by powering the motor directly without the speed regulator.
Too much work, just change the motor and be done.
I was wondering why you couldn't get the chip for that motor. Seems like they are there....
Because i don't know what causes the chip to fail. Could be a shored coil. Don't need to get married to an old tape deck. Change the moter and it is done.
Why couldn’t you have replaced the blown motor IC? I found a ton of LA5531s online for cheap prices. Is it not able to be desoldered?
need suggestions on troubleshooting short circuit (possibly in PCB) in JVC CA-S50, after connecting CD/tape deck component to main tuner amp component while power was turned on...
Great repair
Dave I don't know who would have a problem with how you fixed this cassette deck. However anyone that does take up any issue with the repair most likely doesn't have the ability or the knowledge to do anything that you did.
Some people have an issue just coping with life. Was on a job today and another working doing some work at the same location had a full breakdown, started crying, walked off the job and quit because the property owner asked them to put on a mask before entering the premise. I just stood there and shook my head in disbelief.
It’s a fantastic repair work. Just wondering in case you couldn’t find a suitable salvage motor what are the chances of finding the motor regulator ic and getting the original motor working again?
Did you see the commutator? All worn out it would short and blow the new IC again.
EXCELLENT SAVE!
Can't you replace the LA5531 on that motor ? It's less than a dolar piece.
Great job... as always... 👍👍
.
Does you cat-assistant knock things off your bench. Mine does that all the time, she loves wire ties.
I don't mind this fix, although the chip LA5531 is on ebay.
So... You would rather have a worn out motor with a new chip as opposed to a new motor?
And yes i know sometimes you have to do this, but when a replacement motor is available that is the best option.
Dave you did a great job
I have the same problem.. if a 50k ohm pot is good for the job ???
Hi,by the other hand is a good work.
PLEASE i have an CT-42 with same motor problem... need absolutely an another one... any idea please ?? 🙏🙏🙏
it's a good repair. motor from broken machine repaired a good machine
Like a pro! Great fix!
So now that cassett deck belongs to your kitty lol.
Awesome Work...
I don't see why that boombox being a single deck would have a motor with two speed.
It's just an external speed adjust motor. Can be used in single speed, dual speed and even pitch control configurations.
tell tail was the soot marks just above the motor on the board
I've ordered that size of motors from AliExpress there's actually a lot of them on there and they're really cheap they just take a long time to arrive
He said he did Not want cheap Chinese knockoffs.
@@nrg16108 well that's good cuz they are the original name brand
(@40:43) - near the top right, there appears to be some brownish glue near the regulators and a big cap; I hope that’s not that nasty stuff that becomes corrosive. 🤬
