The Kawai & Teisco Analog Synths Group

Thanks for your input :)

When I got it I was expecting that to be the problem, but since I needed some SSM2044, thought it would be a good gamble.
But when I opened it, it seemed perfectly clean with no leakage.

One thing that I noticed is that some cables are attached to the boards with some kind of glue, not with the typical white terminals (if that's how they are called)...
The seller told me it didn't go to the tech before, so I found that a bit weird...

The one part me and the tech didn't look at was the boards with the buttons on the top of the keyboard.
I'm not sure that was wise, as we could see that the keyboard had some problems with the power supply, with voltages weren't as they should at first, but with some cleaning they were in accordance with the tech manual.
Since the tech didn't charge me anything and spent more than an hour looking at the synth (he said to me he doesn't charge anything if he can't repair things), I didn't want to "force" him to look at that board, but I'm not sure if there could actually be a problem with that board that could cause this strange behavior...


Thanks in advance,
Best

Paulo
