Thanks for the great movies, thanks to them I didn't give up and fixed my 57ES, it probably had every possible malfunction: leaked capacitors in the preamp, cold solder in the power supply, deteriorating sponge that dirtied the head, detached felt after which double-sided tape remained sticky and blocked the mechanism. I think I dismantled the mechanism about 20 times myself :)

I still have my DTC59-ES from 1994/5 bought brand new. Has about 50 hours on it, Rosewood sides works like a charm. The only issue I've had with it is the foam head cleaner pad disintegrated. Clogged the drum and heads. Quick clean and back in business. It's seen around 10 tapes, all Sony. Had a 77ES, sold it, liked the 59ES better. Nice to see an old timer still out here and willing to work on these. Takes patience and logic skills, which you have. Many folks won't touch these. They aren't that bad after the first one, essentially a camcorder/VCR type transport. The ES units use better parts, less Nylon, which break in lesser Sony's. Rock-On!

So I'm vindicated it was not me it was the rot of certain components to in my case of overuse. I turned all electronics into crash test dummies. The stresses on ever level you diagnosed and fixed.The last thing you worked on in this video had been recurring problems with my equipment and never thought about cracking or cracked circuit boards. At least this has put to rest problems I had always were in the back of my mind. Thanks. GOOD VIDEO 😎

Thats seriously going down the rabbit hole. Well done climbing back out the other side with a working machine. I got my DTC-750 and a PCM2300 cheap 2nd hand in New Zealand. Almost identical units, but 2300 is the Pro version and both had head amp issues. I tried recapping the 2300 like how you showed- which worked for a while, but then the distortion came back. I didn't have the bravery to go any further so I sent the mechanism (which had high milage and was really sluggish) to Pro Audio Revival in Romania- who repaired it good as new for a fair few $$$, but it was worth it. He said my head amp repair had been ok, but apparently the pcb was faulty with bad traces, so he replaced it but with new caps. So now nice snappy, perfectly aligned mechanism- which I switched into the 750, runs great. Now I need to tackle the other mechanism (originally from the 750) and its head amp. Although the mechanism is in much better condition than the 2300 one- the reel torque is weak. Often it doesn't have enough to wind the tape- happens in all Rewind, Fast Forward and Play modes- sometimes just stalls, then the unit senses this and stops by itself. Some tapes wont fast wind very far in either direction, when in Play or Record I have seen the tape loop bulging out after the capstan as the takeup couldn't wind on. Any ideas what I should be looking for, how to fix this?

@@BoB4jjjjs there for many different formats that used one inch and sometimes even 2 in wide tape. Recorders which was very common in recording studios that the session tapes were recorded on analog multi-track and then they were mixed to digital and when they were mixed digital they were put on to a 4 mm dat tape. There were multitrack digital recorders that used small cassettes some used a high eight tape others would use a VHS type tape the units that we used to VHS tape were called an A-DAT. 4mm dat or r-dat as it was also known was the 2 / 4 track versions. There was also high bit rate dat which used the same tapes but ran it faster speeds and recorded higher resolution 24-bit. Those tapes however are not compatible with the standard digital audio tape format which is what this is. Consumer format machines use the serial copy management system to prevent piracy by only allowing one generation but the professional decks such as the tascam da30d40 etc have the option to turn off the serial copy management which made them useful in a studio environment. Multiple decks could be synced together because they all run with time code so you could have a bank of recorder players and when linked together all the players would be playing back in sync while your recorder was recording so it could operate as a multi-track system so your performance could listen to the session that had previously been recorded while adding another session and I don't know how many could be linked I know you can link several of the pro machines together and then they could all play back in sync and be mixed down through the mixer. The consumer version of course was stripped down it did not have all the features but the pro decks or actually pretty well made and were used extensively in audio production right through to about 2006 are there about when the transition to hard drive based really took over. Was actually probably a little earlier than that 2002-2003 that the hard drive based recording really took off because by 2006 they stopped making dat machines. there are tons of bootleg recordings floating around that were recorded on dat because the portables were so small. you could smuggle one in to a concert and make a very good sounding recording with just a stereo microphone.

In another Sony DAT model once had filtering capacitors problem around the linear regulators and when the electromagnets activated the mechanism stopped.Also in the mechanism some plastic washers that holding sliding parts were broken and loading action was jammed.Microswitches might have poor contact also,but in general DAT's seems that are repairable enough.

Just a quick advise: I tend to replace the head amp. caps with ceramics (0805). They are cheap nowadays and will never leak. Also they are way smaller than electrolytics. And because the caps are just bypass caps, it's a quick and easy solution with even better bypass capabilities.
@12voltvids Жыл бұрын
I replace with what i have on hand. Not about to order in a couple $ worth of parts and pay 20 in shipping because they might last a few years longer. As long as they last long enough then I am good.

That thing was called 57ES (!) in Europe. I bought one as well for a few bucks which turned out to be a lost cause. I feel kinda sad for the tape. The yellow lid indicates a Maxell Pro series DAT cassette which were of top-tier quality. I can take one of these today, record it on a ZA5ES with 4700+ hours and get consistently low error rates during playback. No other DAT tape besides the Sony PDP-C series is able to do that today. No wonder Ampex put these Maxells in their 467 Mastering Cassette Packs along with the aforementioned Sonys.

Hi Dave. Great video as always. I love how you work through problems to get a machine working, and I have learned a lot from you. The one thing that seemed to puzzle you was that the original tape tray seemed to be 'floppy' and loose, but it seemed OK when you detached it from the transport mechanism? I think I might have an explanation..... You had identified that the timing mechanism on the side was out of alignment so you removed and refitted the bracket which slotted into the big timing gear wheel.. At 9:23 you are tightening the screw to hold the bracket and it looks like the two pimples on the frame were not aligned with the holes in the bracket either side of the screw hole. As a result the bracket went back on slightly out of line with the frame which meant that the rest of the mechanism didn't line up. I would love to know if you think this could have been the issue.

Was sent to hot attics to pull in wiring for ceiling fans on the hottest days of the year while the journeyman was bullshitting in the kitchen having a cold drink while I was sweating buckets. I thought, 4 years of this shit till I get licensed. No f--king way. Went to school to take television production, and did an internship for broadcast TV. Bad timing. No work. Fell into the electronics repair business and loved it for many years. I was making 70 grand a year fixing TVs when the average wage throughout the 80s and 90s was about 40 grand a year. Bought a house and had it paid off in full in 10 years. Left the TV repair business when it was clear that the industry was going to die and got a union job in telecom. I also, in addition to fixing crap, I operated a successful video production company and did hundreds of weddings, and corporate / industrial videos. Now I only work on electronics on my days off, make nothing from the repair, but only doit so I have something to make a video of, because the money is in the revenue that views generate.
