My first five years of my working life was spent servicing and repairing '75s - pretty much everything I know about electronics was learned from that machine! More than 100 head drum changes under my belt.
The mechanisms on these units are so precise, I could watch for hours. The AFM used for audio channels also made these excellent audio recorders, 20 KHz frequency response pure analogue and negligible tape noise. I record SACD from a Sony SCD-1 via the balanced outputs and it adds a degree of warmth but no loss of fidelity. They are way under priced on the used markets. They were about 50k new and replacement heads were thousands of pounds.
@@moldyoldie7888 I tend not to play high frequency tones for pleasure. High frequency tones are annoying regardless of the recording media used. I listen to music, try doing that. On the other hand, these machines are packed with components. The chances of there being a dried out cap somewhere in those audio circuits is high, and it's likely that the original freq response may be somewhat compromised. You got to know what you are doing to get these old machines working to their best.
These were nearly £40k when first released in 1987. A real workhorse machine. The 3000hour service course was a week long ! I still have all the manuals and course notes, and a spare head, as well as BVW-75p number 2. A lot of the capacitors are now in need of replacement, which is quite a job.
This brings back some nightmares. Running tape machines during the 6 and 10 local tv news in '82-3 while in school (I'm a retired embedded control engineer), I operated 2 side by side of this kits predecessor, fed from a cart they wheeled in seconds after the broadcast started. They had to deliver tapes (without error) in proper sequence, I had to deliver proper queuing of correct tape within seconds tolerance (somewhat less forgiving than now in ways... plus adrenaline). . Luckily, most of the job entailed calibration, maintenance, remote (microwave) setup, some field work (at the transmitter), and less dealing with the "talent". Oh... and I used to air The Muppet Show every weekday. Taught me allot. . Every few months there was an equipment failure. 1) isolate it. 2) Immediate Workaround 3) Solve Sigh... love it, hate it.
FWIW, the PB/EE switch selects whether you see/hear input video/audio when stopped. "EE" stands for "electronics to electronics" meaning the record electronics are feeding the playback electronics directly. One reason for the switch is to avoid feedback howl if the VTR is routed to itself.
When I was a kid, my peers wanted bikes or video game controllers. I wanted one of these. That exact machine. After getting a tour of a local TV station and playing with one briefly, I was amazed. The feats of engineering are incredible, spectacular quality from analog tape! It was difficult to go back to my home VHS VCR after playing with this deck. Now the phone in my pocket records better video, technology is amazing.
Great video but... why did you destroy this machine, cutting wire, that unit looks like new? Barely has the dust on it, what a shame. I do not understand. You could fix it later :(
+TVmasterNS hi, thanks for the comments, here in the UK these machines have no value even when they are working. My channel is about taking apart old tech and allowing viewers to see inside things like this that they might not normally be able to see. There is so much wonderful old tech in e-waste that is lost without any detailed record of it.
Oh my. That's the nicest BVW I've ever set my eyes on! I'm about to get a couple of these serviced for many thousands of pounds each. They are still required by archives that are digitising this tape format. Some older tape formats are in trouble because there are not enough machines left in the world to digitise all of the tapes before the video heads wear out. Please use a little initiative and think of the bigger picture - did you check how many hours use the drum, tape path and heads have? You could've used a worse quality machine to destroy. And you mention no detailed record of it - there are so many photos of the insides of these machines. There are massive service manuals detailing the inside of the machines! What, exactly, is the point? My main issue is the the HOURS METER READS 0000.
They certainly have some value. Just need to know how to sell them... You like in UK and not in North Korea, so you can try selling them on Ebay after you put it back together.
I already took apart two of those big broadcast VCRs, a VO-9600P and a UVW-1600P. Found them back in 2011 in a thrift store, 30 euros each. Totally unexpected find, usually the store only has boring consumer grade stuff. Tons of nice parts to salvage... sadly they are way too space consuming to even think about starting to collect them....
I know all the likely mitigating reasons for a different course of action but when the guy started cutting cable looms to take the machine apart I had to walk away and switch off. Up to that point it was good.
+zaprodk Any interesting experiences / comments about them? Given how many bodges i have found on the circuit boards i'm surprised they were as reliable as their reputation implies!
+DextersLab2013 I used the digibeta versions they were solid as a rock in the way they operated. There were so many times where there were in continuities with the vitc or LTC timecode that could be fixed by using the TCR reader switch. I think there was a way where I could insert edit an LTC timecode track over a tape so I could load program material successfully where there were problems with the timecode. When you jog frame by frame the machine would interpolate the other field as indicated by an astrix on the OSD timecode. I'd use this because there was no software we had that would do such a good job. Anyways could you investigate why there is so much circuitry on the back panel connector pcb? Was it input protection? Or to do with the termination switch?
Not quite true, there are some other connections. Betacam (not SP) tapes are interchangeable with Betamax. The linear audio tracks are in the same place. Batteries on some Betacam and Betamax portables are interchangeable. Other details common too, such as BVW22P remote is very similar to some Betamax remotes. ED-Beta (Betamax) uses BetacamSP tapes. Sony clearly had good communications between their domestic and professional design teams.
Most noticeable to me was when he said that there was a "slight increase in video quality from Betamax to Betacam". I have a bunch of Betacam sp cameras and decks that I got from ebay over time and I'll put them up against a standard dvd format any day. As far as video quality goes anyway.
>I'll put them up against a standard dvd format any day DVD is far superior. 720 x 480 trumps 340 TVL, especially since DVDs containing film-source video can be played back with progressive scan, i.e., 480p, whereas Betacam SP is always natively interlaced.
I disagree. DVD is roughly 7mbps. BetaSP is always digitised at 10bit uncompressed - 240mbps. If you put film-source video on a BetaSP tape then you get 2 fields of interlacing per film frame. That effectively makes it progressive. You would certainly be able to digitise it and make it progressive. V short answer, sorry - just had to correct though. No bad feelings intended.
Here in the Philippines, the Betacam was used nowadays by ABS-CBN, TV5 and GMA networks. PTV and IBC use VHS, while the other TV stations use digital tapeless master equipments like AVCHD, DVD and hard disk drives.
Esta gran tecnología para mi es muy interesante no obstante ya obsoleta para estos tiempos pero que sin embargo representa un Icono de la alta calidad en los estándares del Video de siempre que represento siempre lo mejor de lo mejor no me cabe duda, con la miniaturización es posible prescindir de estos equipos. yo en lo personal me daría el gusto de Operar uno de estas maravillosas maquinas aun en esta época de grandes cambios tecnológicos estoy convencido de que son toda vía de gran utilidad por su gran calidad.
Shame to cut wiring harnesses. Machine looked in good condition. These decks still command high prices here. Betacam cassettes will work in standard Betamax vcr (not SP tapes/wear heads out). SP (small) cassettes will work in ED Beta vcrs.
The pronunciation difference makes me chuckle. On your side of the pond it's a long B as in Beetacam but here in the US, it's a short B as in Baetacam.
This was both nauseating and fascinating. It pains me to see old tech disassembled, but at the same time I wonder if the parts are a reasonable trade-off.
Thanks! It was an amazing machine, the video on the dynamic tracking is pretty good too if you have not spotted it already. ua-cam.com/video/10A066JNe6U/v-deo.html
Just bought a BVW 75 Betacam SP but it didn't come with any of the cords necessary to connect it to a tv/monitor. I only came with the electrical cord. Do you know which cords I need to make this machine fully functional? Thanks for help on this issue.
For what? I could put six SP machines in a single 70” tall rack vs several racks of BVH2000’s or a room full of Ampex VPR2B’s. For sports replay use the 75 was great. Smaller & lighter than any 1”, plus with a good remote panel which gave the op multiple cue points it was king until HD Cam and the EVS came out.
It's because of people like you that is the reason why these machines are becoming so much harder to find. Let's see you do this to you're favourite tower computer hey.
Broadcast equipment just doesn't hold its value very well anymore. It's often possible to find a good working US$75,000 HDCAM SR deck on eBay for $5K or as little as $1500, and these things are the workhorse of the industry!
Yea, it's surprising how cheap things get when both the product and the format become EOL. Just after making this video i missed out on a Sony DVR-1000 D-1 Recorder.
Great video. Thank you! Big thumbs up! I wished you could have shown all cards in detail. (Edit: I have learned that I will see them in Pt.2. Excellent!) I have tons of Sony Umatic and Betacam SP machines sitting at my store. Nobody wants them....
+Max Koschuh Thanks Max, U-Matic is older even than Beta, huge tape drums and make great mug coasters :-) Yea, it's a shame these are not wanted anymore, i think though some of the newer ones will still be wanted because they are be capable of playing back both the analog and digital versions.
If it´s broken, ok. But what the hell your doing? It was a working machine. Cutting wires, the annoying way you hit the switches - Fine-Motor skills is not yours? Its cool if somebody have the skills to repair this stuff, but destroying old electronics !? Take it apart and then reassemble it,that would be great content ;-) (Sorry for my english...)
hi, the BVW-75 was a very popular machine, there are usually 2-3 on ebay at any one time and here in the UK they sell for £10-£30 depending on condition. The one in the video was well used and had some faults, it simply was not worth repairing. Instead i was able to entirely take it apart on camera so others can see how it works, which is one of the main reasons for this channel.
Well now you know where your coffee cup coaster came from....... Must strip the last one, but it is so darn heavy and it is on the top shelf under a whole load of other stuff as well.
hi to all there no need to cut the head looms just take side panels away till you get to the wiring looms i am a pro at talking them apart for speed i know for the video
The only difference between the Sony pvw-2800p is that this one records four channels of sound, but if the 2800 has a Sony PVW-216FM audio module or even better Michael Sellman LTD, the sound is much better when recording both 2 channels and 4 on the Sony PVW-2800P model than on the Sony BVW-75 model and the stories that 75 writes better a myth that I can dispel by comparing these two models during recording and playback and at a price of 75 it was 3 times cheaper than 2800. how it breaks back is due to a flimsy or unfinished lpm, I am silent for the electronic part.
@@ЭтоДрючинский аппараты конечно хороши .но сложно эксплуатировать в быту -капризная механика ( или уже ресурс на исходе ).пользуюсь несколькими моделями и периодически виснут с кассетой внутри . собственно поэтому держу несколько экземпляров ( 7 шт) хотя хватило бы пару рекордеров и плеер .
This prof., commercial VCR Deck can play and recording on Betacam with the smaller Cassette and the larger Cassette in Betacam SP.... But not play a Betamax Cassette! The prof. portabel Cameras with Betacam SP can recording only on the smaller Cassette with 30 Min. , not the larger Cassette from the Studio.
CTDM is Compressed Time-Division Multiplexing; this is the raw video format used with Betacam and Betacam SP. Personally I was expecting more metal in the threading mechanism. The threading mechanism in the majority of U-Matic decks was all-steel.
Basically with a second machine, if you have the proper cable, you can edit in CTDM and your generation loss is "less" compared to doing a dub or edit in Composite....
You spent a lot time of time creating and uploading this video and no one in north America understands your pricing language. Wtf did you say you paid for this old VCR?
VHS won over Betamax because Sony wanted to charge a high levy for use of the patents on both recorders, players and the tapes themselves. The VHS consortium had lower rates, so could make a much cheaper cost machine which was a major advantage. Plus Sony was not exactly enamoured of the largest user of video, the porn industry. But the masters were all made and supplied on Betacam SP tapes though, much lower generation loss.
+SeanBZA Oh yea, that just reminded me, didn't Sony have a funny policy where they could choose what went onto their tapes? Which is why porn favoured the VHS tapes that had no restrictions.
You can get Audio to PCM/PCM to Audio units that enable you to record HIFI audio onto BETAMAX tapes so It would be a shame to destroy the unit so do a simple disassemble and reassemble no complete teardown, It appears that the PCB cards are in sockets so you could remove them one and show both sides to the camera and reinsert into its slot and repeat till you have shown the camera all PCB cards and put the thing back together and use it with the Special SONY Audio to PCM PCM to Audio unit and use it for sound editing.

hi you know you said £25 ebay working not any more i had them all like you i pulled them apart to fix them up kingswood hire place had them it was better to have them as cash in the bank was doing bad at the time they sound ace used for sound i have 50 plus now all working you seen the prices on ebay now
hi again i just done working on the last i have of theis model they are very well made decks yes the SONY A500P can do a better job i have 12 of them but the power the A500 range use i have to keep the running costs down so i use the older decks alot of the time only for audio play back there's not alot in the running cost of a 1/4 inch reel to reel like the RS1700 or a otari mtr 12 1/2 inch 4 track you see i have to bill anybody for the power cost and the job funny thing i have saved alot of betacam sp decks from the skip if like me you can get alot in the same place and pull parts as parts decks they can be saved the space is the thing 50 plus betacam decks takes space just me and a big lady cat no lady trying to tell me what to do
Разница между Sony pvw-2800p только в том что этот пишет четыре канала звука но если у 2800 стоит аудио модуль Sony PVW-216FM или ещё лучше Michael Sellman LTD звук гораздо лучше при записи как 2 каналов так и 4 именно на модели Sony PVW-2800P чем на модели Sony BVW-75 и рассказы о том что 75 пишет лучше миф который я могу развеять сравнив эти две модели при записи и воспроизведении и по цене 75 в 3 раза дешевле стоил чем 2800. Механика у 75 полное гавнище так как не успеешь сделать как он обратно ломается это связано с хлюпким или недоработанным лпм молчу за электронную часть.

The only difference between the Sony pvw-2800p is that this one records four channels of sound, but if the 2800 has a Sony PVW-216FM audio module or even better Michael Sellman LTD, the sound is much better when recording both 2 channels and 4 on the Sony PVW-2800P model than on the Sony BVW-75 model and the stories that 75 writes better a myth that I can dispel by comparing these two models during recording and playback and at a price of 75 it was 3 times cheaper than 2800. how it breaks back is due to a flimsy or unfinished lpm, I am silent for the electronic part.
The pvw couldn’t do slo mo plus the BVW could use Betacam tapes if need be.
I already bought one but which of the wires do I need for the audio & video inputs?
Sweet machine, love the transport system. What was this machine worth in its day ??
I believe they were around £5000.
Nope.. 18k in 1999. The head cost more than 5k
Немного жаль старичка ! но обзор великолепный , спасибо !
Так порезать провода... Я чуть не закричал когда увидел это(
Мне бы такой...
@@ЭтоДрючинский аппараты конечно хороши .но сложно эксплуатировать в быту -капризная механика ( или уже ресурс на исходе ).пользуюсь несколькими моделями и периодически виснут с кассетой внутри . собственно поэтому держу несколько экземпляров ( 7 шт) хотя хватило бы пару рекордеров и плеер .
This prof., commercial VCR Deck can play and recording on Betacam with the smaller Cassette and the larger Cassette in Betacam SP.... But not play a Betamax Cassette! The prof. portabel Cameras with Betacam SP can recording only on the smaller Cassette with 30 Min. , not the larger Cassette from the Studio.
CTDM is Compressed Time-Division Multiplexing; this is the raw video format used with Betacam and Betacam SP.
Personally I was expecting more metal in the threading mechanism. The threading mechanism in the majority of U-Matic decks was all-steel.
Basically with a second machine, if you have the proper cable, you can edit in CTDM and your generation loss is "less" compared to doing a dub or edit in Composite....

This was a better teardown, though still uneventful.
Quite a nice salvage though, especially the motors, jog wheel, and transistors.
+Spirit The VU meters are really nice too, self-contained so very easy to interface with something else.
You spent a lot time of time creating and uploading this video and no one in north America understands your pricing language. Wtf did you say you paid for this old VCR?
Lol, 40 quid... Aka £40 or about $50
@@DextersTechLab thanks
VHS won over Betamax because Sony wanted to charge a high levy for use of the patents on both recorders, players and the tapes themselves. The VHS consortium had lower rates, so could make a much cheaper cost machine which was a major advantage. Plus Sony was not exactly enamoured of the largest user of video, the porn industry. But the masters were all made and supplied on Betacam SP tapes though, much lower generation loss.
+SeanBZA Oh yea, that just reminded me, didn't Sony have a funny policy where they could choose what went onto their tapes? Which is why porn favoured the VHS tapes that had no restrictions.
22´47" ouch - that really hurts !!!
You can get Audio to PCM/PCM to Audio units that enable you to record HIFI audio onto BETAMAX tapes so It would be a shame to destroy the unit so do a simple disassemble and reassemble no complete teardown, It appears that the PCB cards are in sockets so you could remove them one and show both sides to the camera and reinsert into its slot and repeat till you have shown the camera all PCB cards and put the thing back together and use it with the Special SONY Audio to PCM PCM to Audio unit and use it for sound editing.
+DAVID GREGORY KERR this is betacam, not betamax. They are very different. The recorder was completely scrapped in the making of the video.
@@DextersTechLab Such a waste of a good functioning recorder 😔
Would of thought there would be much more custom logic by that date.
There's more than 40 quids worth of XLR connectors on the back panel!
+Alan Cordwell I'm not sure if there's £40 worth but they are all good quality Japanese made ITT Cannon, defo for the parts box!
Thumbs up :)

Nice Video Sir.🤩.In Which Country Are You Belong.🤩. Very Nice Video.🤩.

Debería dedicarse a desbaratar chatarra, usted es muy ordinario para tratar estas espléndidas máquinas, que ordinarez, excelsas máquinas en manos de destructores....
Обзор отличный но не смог смотреть дальше, после того как увидел откусаные провода. Не люблю когда портят технику тем более подобного класса.
Я так же. Поставил дизлайк(
I need replacement head for my BVW 75.
Somewhat unobtanium now, best bet is to find another machine with less head hours.
@@DextersTechLab Currently I have 2x BVW 75. RT56 TP7-TP8 = ~90-100 mVpp. It should be 150-250 mV.
hi you know you said £25 ebay working not any more i had them all like you i pulled them apart to fix them up
kingswood hire place had them it was better to have them as cash in the bank was doing bad at the time
they sound ace used for sound i have 50 plus now all working you seen the prices on ebay now
When legs pull slow is ok
to see you in ruin The amazing video machine was absolutely not fun. It's sad
hi again i just done working on the last i have of theis model they are very well made decks yes the SONY A500P can do a better job
i have 12 of them
but the power the A500 range use i have to keep the running costs down
so i use the older decks alot of the time only for audio play back there's not alot in the running cost of a 1/4 inch reel to reel like the RS1700
or a otari mtr 12 1/2 inch 4 track
you see i have to bill anybody for the power cost and the job funny thing i have saved alot of betacam sp decks from the skip
if like me you can get alot in the same place and pull parts as parts decks they can be saved the space is the thing 50 plus betacam decks
takes space just me and a big lady cat no lady trying to tell me what to do
Thats a lot of smd in a device that old!
would have cost a fortune back then.
+marcel.o r I have it on good authority that they were about £7000 back in the mid 1980s.
Roughly $50 for a machine, that once cost $50.000, which at the time could buy you a new Ferrari.
Beat A Cam? Wot?
Разница между Sony pvw-2800p только в том что этот пишет четыре канала звука но если у 2800 стоит аудио модуль Sony PVW-216FM или ещё лучше Michael Sellman LTD звук гораздо лучше при записи как 2 каналов так и 4 именно на модели Sony PVW-2800P чем на модели Sony BVW-75 и рассказы о том что 75 пишет лучше миф который я могу развеять сравнив эти две модели при записи и воспроизведении и по цене 75 в 3 раза дешевле стоил чем 2800. Механика у 75 полное гавнище так как не успеешь сделать как он обратно ломается это связано с хлюпким или недоработанным лпм молчу за электронную часть.
Bet your kicking yourself now ! Just checked and prices range from £350 to £1000 LOL
Trashing any technology like this is a disgrace.
Wrong! The last four that sold on ebay uk averaged less than £100 each.
what does this VCR do? www.amazon.com/dp/B07HMVNS16
Looks like a data recorder, like the Teac unit i looked at a while ago but based on vhs
DextersLab2013 can do a review on it? i think its so cool how they tied them together
sure, if someone buys it and sends it to me! It's $450 though! :-)
DextersLab2013 i emailed them they will loan into you for shouts out !!
Just bought a BVW 75 Betacam SP but it didn't come with any of the cords
necessary to connect it to a tv/monitor. I only came with the
electrical cord. Do you know which cords I need to make this machine
fully functional? Thanks for help on this issue.
Nick Charles if you're asking that kind of question it kind of worries me. Do you know what it is you actually have...?

Composite video would be a good start, you would likely need a BNC to Phono cable. For audio you probably need a XLR to phono adaptor.
