[sdiy] polymoog repairs

[May, Tony]

Well, having just brought mine back from the dead, let me offer what
advice I can. I am assuming you don't have the service manual/schematics
for it. Having them was a BIG help, at least for me. I would work on
getting sound out of her again before worrying about the filter. The
best place to start is to check the voltages coming off of the power
supply board. 

I haven't yet pinpointed the exact cause of no sound on mine, but I was
able to correct it by replacing all of the easily accessible cmos chips.
(i.e., the ones in sockets and not soldered straight to the boards.) 

Good luck!

Tony

hello

i have a broken polymoog (which poly isn't?).  ever since I've had it,
the 
filter has not worked, now it does not make a sound.  I am wondering if 
anybody could tell me which section inside is the filter so I can poke 
around.  I have no electronics ability really, but like a recent member
said 
about a CR-78, it is a wonder what one can do with simple procedures.  
Thanks.

I also have a broken CS-5 that makes no sound.  anyone wanna crack that?
