Vintage Synth Repair

Hello Ambrosia,

I`m also from germany, and I think, like PeWe, that you just have to 
change the el-foil from the display. I don`t think, that the PSU has 
any problems, because you have writen, that your synth works 
perfectly. The hardened brown stuff, that you have described could 
be some kind of glue, which fixes some components on the PCB. 

I would think, that somewhere near the foil sits a little cube, 
which should be the inverter, which powers the e-foil. That could 
also be the problem, why your display is dark. But in most cases it 
is the el-foil. Like PeWe I also have made good experience with 
www.midirakete.de. Two years ago I have bought a new foil for my 
Emulator II. And it looks and works pretty nice since the day I have 
build it in. Because it is the cheapest thing you could do, I would 
first change the foil.

Best regards and good luck.  :-)
Heiko
