Vintage Synth Repair

Hello!

I just bought a Roland SH-1000 with front panel completely painted 
black. Does anybody have a good picture, maybe a user manual diagram 
of the inscriptions silk screened on the panel. A good quality photo 
can do the job.

Thanks!
Arnaldo.

Hey dude,

Your in luck! I just took some pictures of my studio set-up yesterday 
so I've up loaded a fat photo of the front panel into the photos 
section. Keep clicking on the photo till it shows it at full rez' 
(two clicks)
I love my SH'! It's a helluva a lot of fun and it's got such 
character! But goddamnit, It stopped working! First the keys were 
really noisy, even with all the oscillators off. Then the oscillators 
stopped working all together, exept for a  very faint unpitched 
squeal. Does anyone know what might be causing this? Is it relatively 
easy to repair, or am I better off taking it in to be repaired? Any 
help would be wicked!

Cheers,

Wotzit.

Thanks! But you forgot to tell me the URL of your site! ;^)

I'm about to get the service manual for SH-1000. I opened it and the first thing I noticed was the presence of several "custom made" ICs. They are not exactly custom made in the sense the IC was designed for Roland. Roland just took a bunch of components, solded into a single small board and covered it with epoxi. I believe this was a security measure to avoid circuit copies but it makes the repair far more dificult.

Let me take the service manual and maybe I can help you with your SH-1000.

Cheers,
Arnaldo.

Hello!

The photo is here! It's in the vintagesynthrepair photos section ( to 
the left side of the screen).
Funny thing, I decided to take one final crack at the ol' SH' last 
night. When I opened it up, I noticed that I had knocked a umm.... 
small silver thing that looks a capacitor with eight connectors that 
plugs into a blue thing... Anyway I had knocked it loose during a 
previous repair attempt! Oops! So the synth is now back to the up and 
running stage, which makes me really happy... But it's still freakin' 
noisy! Is it possible that the connecters(white plastic plugs)just 
need a good cleaning? 
Thanks for the help!

Wotzit.
