Never knew this little guy had so many miniature moving parts which makes it very difficult to repair. Just by watching you repair this. Congratulations on the repair work Dave.
I own one of those TCD D7 machines and I stopped using it because it acted like it was dirty . Sometimes it would work and sometimes not. I’ll be getting it out this weekend now. Great sound ing.
I feel your pain, I just had to fix my D7 and re lubricate it. I kept having to adjust the timing cam gear because wouldn’t put tension on the tape after ff or rw. I found out it was 2 teeth off (thanks sony for no information to set the timing in the service manual)
I figured it out by taking photos of a working unit before disassembly. No data in service manual and those that dud figure it out are asking 49.00 o. eBay to sell you the info. I just gave 5ge sellers the finger.
@@12voltvids any chanche you can share these pictures? I'm having a very hard time trying to align them up and even after looking at vids the damn thing just refuses to work and spews out error 10s and 11s
Glad you could find replacement parts. I currently have a D100 in service that has a broken clutch gear. There's only one source for replacement parts. It's in China and the supply situation isn't that good.
I know it's off Topic but I've just read that over 20 Horror Films wher Released on V H S This year 2023..? And that the Sun Company still makes Video play Machines and Small Amount of V H S blank tapes every year..yeh its Coming back and won't have to keep fixing my old V H S every now & then. 🇬🇧
Hi Dave, my TCD D7 only works when it's been on the power supply for a couple of hours. When "cold", I get all sorts of errors, it doesn't open, playback is quiet and distorted. Is tha cap related, maybe? In addition to the obvios SMD caps, I think there's a differnt type on the PCB as well. Do you know what those are?
30:38 It is not the DAT format that is junk, it is the tape, as a physical medium, that is junk itself no matter the format. It just so happens that the DAT format recordings were unfortunately the most susceptible to degradation with aging. Tape is rubbish as a long term medium but, hey, it got us through half a century or more and DAT got us through 20 years or so, from the early '90s onwards and if you add it's sisters and brothers (DA88, Hi8 etc.), it must add up to at least a quarter of a century. As to the people that say DAT is junk, remember that back in the day people opted for miniDisk. Now that was the definition of an inferior, throwaway format but they sold like hot cakes. Compare that with DAT which, due to its prohibitive price, no-one even knew about. If compact cassette had been made even better, that would be the default format and the recordings on compact cassette seem to last longer. What DAT allowed was easy time alignment and the full power of digital processing when editing. Oh, no sound degradation after multiple copy generations, theoretically at least, was the major boon that got people hooked. Sadly, given the amount of over-processing done in studios these days, there is no perfect format - physical format that is. Hard drives and flash or solid state drives contain electronic circuitry and are not designed to be used as cartridges. More importantly, we do not know how long solid state drives hold information for and in case of partial physical damage, all or large portions of the recordings are lost even if the extent of the physical damage itself is minimal (e.g. a cracked chip). One could argue though that hard drives (magnetic ones) are the natural successor to digital recordings on tape. So far it seems that hard drives hold information well even though we have not yet passed the half century mark. It is the electronic circuitry components (i.e. capacitors) that age before the recording medium itself in these. That is probably their major weakness - that and technological obsolescence which at the moment seems to have a 5-10 year horizon at most.

You have no idea.
🕺🕺🕺DAT works DAT does. DATs great. Gonna need bionic eyes to work on kit like that. Great fix!
I don't win every battle with these.
I saw part one. Great that you found the parts!
Edit: I miss the days when radio stations had disc jockeys and spun records. I know, life goes on.
They still do. One of our local FM stations still spins vinyl. The one I listen to has live djs but the music plays from computer.

I swear you can repair anything!
Well done Dave, not a simple job at all.
The owner will be happy as a sand piper :-D
Happy days Great repair job 👍👍

Sure they are. Lol
29:06 I believe it was three you could chain together to get up to 24 track recording. I have a DA-88 and DA-98 (24-bit) here.
Perhaps. Someone told me 8 but what do I know. I don't have any.
I have never looked up the spec.

Didnt know DAT walkmans existed
Lots did. Sony had a bunch of them tascam had some pro units, fostex, casio, Denon. They all had Walkman sized units.
I have seen a 3D printed cog wheel available on eBay for these machines,not sure which one it is though.
I have never had any success with 3d printed parts.
And concepts as well
Ribbon cables alwaya get me, looking at them they alreasy break.

I miss the kitty. Guess the kitty is gone.
I just haven't used that opening in awhile. The cat will make an appearance from time to time.
People haven't figured out use gears like a resist watch has brass
These things cost enough when new. Metal gears would have made it even more expensive.
the postage to Israel-would be a fortune (another success)
Have no idea. I shipped to Toronto to someone that was going there
Nobody asked but ,Arnold uses a Sony DAT in True Lies (Bedroom Scene) while sitting in the dark
I disagree the design was good but the DAT system was complicated, to miniaturise it to that level was a big achievement.
About the only thing more complicated than dat was the digital video camcorder. DVD and Blu-ray camcorders are another complex device.
