My VCA is toast, Help!
Was playing on it today and suddenly, crackle and bam no sound. Turned volume all the way up and I can hear the osc and filter working but there is tones of noise and distortion so this means my ba662a just bought the farm right? Or could it be something else?

Re: My VCA is toast, Help!
so that means you still have your 6110? are they socketed, can you swap it in and see if it fixes it? seems that would answer the question pretty quick...Altitude wrote:Was playing on it today and suddenly, crackle and bam no sound.

sucks to have that chip die... so with the 662 was it "more like a 303" than with the 6110?

Ok, got my surgury gloves on and thankfully had enough brains to save the 4 parts I removed when I installed the 662a and found my mangled ba6110 (4 pins broken off). Replaced the parts, did some creative solder sculpting and Viola! Problem still there (same thing).
Not the BA662a, thankfully. Did the normal procedure of reflowing everything and did a good going over with the techspray and FIXED!! So my normal "jump to the worst possible conclusion" reaction (I'm kinda a Nietzsche fan) proved to be a little hasty, which is normally the case.
Looked like something must have bridged or oxidized
