Hi Tony, Thank you for another great video. I won’t be doing a tape deck anytime soon, but it was very interesting. About the linseed oil... my wife and I nearly lost our house.. and our lives because of some rags spontaneously igniting! We had just redone the main floor’s parquet. We woke up in an inferno! Anyway, I hope people won’t underestimate how little it actually takes... Cheers Mark
Comment on production and Caps starting at around 21:00 mins in this video. I believe designers were fully aware which component goes where and why. There is cost saving point. Yes, of course! But I think that they placed on purpose Mylar instead of Electrolytic and vice versa. They for sure did NOT throw in just like that any component. There were a lot of designing, engineering and testing to the smallest details to design perfect circuit for the product they were planning to release. Thanks Tony for your yet another greta video! Much appreciated! ;-)
lol, actually they DID throw in whatever was in the parts bin. This happens in all manufacturing, there will be different components and sub-assemblies in the same model in the same place through the run. The engineers design something perfectly, then the bean counters get hold of it...I don't think that is what is happening in the film vs. electrolytic conversation, there has to be a particular reason there, but across the board manufacturers use up the surplus parts on hand if it will work in a particular instance, even if it means a reduction in performance or quality.
@@seanobrien7169 OK, I get your point. But I was rather thinking about in which place is better Film than Electrolytic. Again, I don't think designers were not checking and testing audio signal and choosing which type of component is better for particular task. But hey, you may be right all along! I am first to say I don't know for sure. Rather than that I am making an educated guess.
Thanks for discussing the leads issue again. I’ve tried doing that since you mentioned it before, and it does give a much more “original” appearance in addition to the other benefits. Oh yeah, personally I enjoy solder chat time. I learn something new every time I watch one of your videos Tony. Thanks for the continued learning sessions, where everyone can say they were taught something.
I really enjoy restoring old tape and cassette decks and find it therapeutic recapping and replacing components. The end results are always so satisfying. The journey is the point. Plus the fact that I always learn something new. Love the channel Tony..thanks for all you do. :o) xx
Tony your great instructor, I've learned a great lesson from you today never work on the cassette deck. May I Paraphrase Father Mulcahy from the TV show Mash 4077 " a little jocularity" .
One of my friends in Los Angeles invited me to check out his home sound system in his double wide trailer. He even let me hook my iPod to it and play some *gasp* MP3s through it. I was totally stunned. Easily the best home system I have ever heard. He swore by his cross-overs but his tweeters were fairly high tech. He pointed out there was hardly any distortion at all. We could talk to each other at a reasonable volume and the system was playing LOUD! We stepped outside of the room and he closed the door. You could barely hear the bass thumping. This was a trailer park after all! 😅 My MP3s were encoded at a fairly low bitrate but they were from the highest quality digital source. Nostalgia is fun and inspiring but at the end of the day I want to also utilize what modern technology has for us.
If the MP3s were particularly low bitrate (in my experience, less than 192kbps, although that's very content dependent), it probably sounded really awful to the audiophiles. Or at least that's what I found out when I was building my OpenDAC HD - it really brought out the MP3 artifacts on a test track I was using. Play a FLAC instead and it gave just great audio instead.
Greetings: Because the capstan pulls the tape at a constant speed while the take-up pack diameter increases as that side is played, the take-up rotation speed slows down. In order to accomodate that reel speed change there is a slip clutch on the take-up reel; actually on reverse play machines both reels have the clutch. So, if you think the out of round condition of the reels makes a difference in the tension on the capstan speed, I contend that variations in the clutch slip has an equal or more affect on capstan speed. I have never seen either affect documented, but think the separate take-up motor on three motor decks provides the least impingement on capstan/tape speed variations.
Note that the felt pad, in the pickup reals, are the clutch that controls the tape tension. They need to be in good, clean shape. Also, when installing the new pinch roller, check the alignment of the capstan and roller. In those era of decks, the capstan brass bussing had a tendency to wear, causing the top of the capstan (against the roller) not to have the same pressure as the bottom. Which would result in the pickup real having influence on the tape.
How would you adjust that do you use shims or do you just have to replace the brass bushing? I wonder if all the felt pads should just be replaced as part of maintenance.
@@alphonsefrascato3342You had to replace the bushing, and for the felt pads, if they are flat and smooth, you can replace them, or very, very, very lightly fluff them up. The way you test them is to grab the tip, and you should have some good torque, but not stop the iderler wheel driving the pickup.
One way to check smooth operation of the takeup reels is to FF/REW a large window cassette with a precision mechanism, like a 1986 TDK MA-XG. The way the tape packages when going from one hub to the other will tell you a lot about the stability of the deck's reel operation without the influence of the capstan/pinch roller.
Check the W&F figures of the two sources of new rubber pinch rollers you receive Tony. There has been alot of debate about rubber quality and how new pinch rollers perform if they are not manufactured correctly, this is really important. I purchased a couple of new ones for one of my decks (they weren't cheap), quality was poor and over a short space of time gave high W&F figures and caused tape transport issues.
This is especially important on dual capstan machines. If pinch rollers aren't manufactured precisely, there is no way in hell that a constant tape tension in the loop can be maintained. This will cause W&F and, more importantly, also damage the tape, especially the thinner 90 minutes ones.
Just a quick comment regarding the Ultrasonic cleaner. The tap or distilled water you pour in needs to be de-aired for the unit to perform well. That is simply a cycle of a few minutes and it takes care of the air in the water. Or, when you pour water in the unit, add 3-4 additional minutes to the time of the cleaning cycle.
When I was doing pocket watches I found out Windex (or cheap generic window cleaner, the blue streak free stuff) is a great cleaning solution for most materials in an ultrasonic cleaner. Cleans grime, is safe and dries very quickly.
With regards to your capacitor query in the audio chain . It is all about impedance matching between stages . different caps present different impedances . ie like 50 ohm coax between a 50 ohm transmitter and a 50 ohm antenna
When I replace capacitors that are located next to a heat sink, I always go up in voltage wherever possible (size permitting) because doing this is the same as getting higher temperature rated capacitors. This is useful when you want a longer service life out of the device! But that's just the way that I do it..
Sometimes it's about teaching the person to listen, not hear. Listening and hearing are two different things. Maybe the people don't hear the difference because they have not been taught how to listen. It is kind of like the difference between a casual jogger and a track and field competitor.
I so want to give you a smart-alec response, but what you say is right. My wife cannot identify issues with audio on her own, it is just music to her. But when I point something out and maybe show her how it should sound then she gets it. I hate the audiophile snobbery, sort of like the wine drinker idiots (and yeah, I apologize for that, hey, if it is your thing you should get into the nuances, just realize that you are a complete boor to everyone else) but then I hover around the fringes myself.
@@seanobrien7169 I wasn't trying to be a snob. I used to design pro audio for a living. You have to listen, not just hear to get better at it. But I agree, you either get it or you don't. You either care or you don't. I do enjoy well reproduced music. Some people like cars, some are passionate about exercising, others cooking or wine/bourbon/beer etc.. Not sure why if you enjoy listening to quality audio that is a negative and makes that person a snobby bore. I don't push music listening on others. I enjoy it. If you don't and like something else fine. Would love to understand why that prejudice is out there for audio but not cars for example.
@@jked7463 You took that a bit more personally than I had intended. I suppose anyone with any passion can be a boor to others without that passion. You sort of missed the whole point of my response, but that is okay. Happy listening. I am on some Doors today, just felt right, though I am eyeing that Herbie Hancock album. Maybe a little Watermelon Man next...
@@seanobrien7169 oh, ok. Wasn't sure. Thanks for clarifying. I have had a good amount of people putting me down for saying I can hear the difference that a good system can provide. They can't hear the difference so therefore I must not be able either.
I assume the camera will default focusing on the center point, which is why being slightly off-center will tend to move the focus on the bench instead of the hands. Some cameras have more advanced focus features ("AI") but a lot of that either works only in the photo mode or are designed for faces and pets. One feature that would help is activating the zebra stripes or focus peaking, if you have them.
Just went to terrysrubberrollers.com the index page there says he's fighting pneumonia and Covid and everything is on hold. So we should all say a prayer for him.
Hey Tony, I'm having a problem with my CTF-1250. I'm the original owner from like the late '70s or early '80s. I replaced all of the belts as well as the idler tire. However two problems remain. None of my buttons are responsive. I ohmed out the cable to the keypad assembly and get continuity on all wires. Any idea as to what the problem might be? When I put the tape in I get the temporary solenoid operation to release the brakes on the supply and takeup reel spindles. Also when I press the auto play button when I power on the unit it goes into play mode but the takeup reel spindle sometimes stops. The cassette is good and is not binding. I also found that with the tape out and putting it into play mode, when i put just a small amount of resistance on the takeup reel spindle that the motor stalls. It seems like it just doesn't have much power. Any suggestions? Could that be solved by trying to clean out and refurbish the motor like you did?
hola, me llama la atencion que cambies los condensadores de la fuente sin medirlos primero ??, para saber si estan mal, o los cambias por las dudas. Gracias
Just as a warning, it is both extremely hard (and therefore difficult to work with) and very heavy. Usually I find myself drilling and tapping holes in it for a machine screw rather than using a wood screw.
Good morning . Can you make a tutorial about non polarized electrolytic capacitors vs electrolytic capacitors in audio path circuit, and if its better to prefer non polarized?
I've leaned that you want to cut the leads before soldering because cutting after soldering will stress the solder joint and potentially damage it, so in time you end up with a cold solder joint. And when mounting component on a PCB you want to bent the leads 45 degrees before you cut them, to get the best compromise between mechanical strength + electrical connection and ease of removal if needed. A 90 degree bent lead will give you good electrical connection and mechanical strength, but you swear a long distance if you have to replace a component mounted this way. (I hope "you swear a long distance" is a good translation of the Danish expression "man bander langt væk")

Hahaha I can just picture the little three year old using the cassette deck as a piggy bank back in 1982...Thank God he forgot about it after the one penny...
Interesting that most people playing these tapes used portables costing less than $50. Clearly much audio compromise, but I bet there is an amazing amount of innovation in putting all this stuff into a small cheap package.

Hola Nelson, Intenta usar el diodo UF1004 en lugar del 1n4148. Tienen una característica más cercana al estabilizador MV-1 original. Los cables del UF1004 son más gruesos, por lo que es posible que deba abrir un poco los orificios en la placa de circuito. Espero que ayude. Hágamelo saber.
@@xraytonyb Okey muchas gracias Tony, los ubicare y se los pondré, te estaré escribiendo, para decirte que tal funciona, muchas gracias.
Hahaha I can just picture the little three year old using the cassette deck as a piggy bank back in 1982...Thank God he forgot about it after the one penny...
Terry's health is an issue for him, so he's NOT filling orders at this time.
Oh no. That's not good. Not good for us restorers either. Hope it isn't serous. Wish Terry the best of luck.
Interesting that most people playing these tapes used portables costing less than $50. Clearly much audio compromise, but I bet there is an amazing amount of innovation in putting all this stuff into a small cheap package.
