i just had EXACTLY the same problem after a blown fuse due to a bad diode ... by the time i got the PS fixed up I have a constant stuck note with a little LFO on it -frequency is controlled by the LFO slider ... most other panel controls seem to be working too ... I found THIS page on Old Crow's site and it sounded exactly like the problem - so i tried changing out the chips on my SH board and STILL the same effect ...
one thing i DO notice however is that the 4016 chip is 'full on' ... each pin is at max. voltage - 15v through the Vcc pin and 8.6v through everything else ... so i guess that explains the stuck notes ... but I'm a bit a bit of a loss to explain WHY this is ...
ANYONE?
