ok, replaced cd4016BE with the new chip from mouser. worked with the new chip, but didn't fix the problem, so it obviously wasn't that. any other ideas before I take it to a tech?

love my moog source, but it's got a slight problem. sometimes when I play there's what seems to be a problem with the keys, like it's momentarily for a split second jittering between notes. it doesn't happen all the time, and seems to happen on some keys more than others. but it's really annoying ...

ok, found the part via Mouser for 52 cents, will see if replacing this works.

ok, I went inside the source, and the only chip that I think it could be is in U32 and is labelled cd40168E r049. I googled the first part and it came up in electronics supplies, so I could order this. I also noticed that this chip was sticking up out of its socket last time I opened the source, I ...

many thanks, that helps just enough for me to see if this is something I should handle or not. Yeah, I've definitely gone inside synths before and caused more problems than I fixed. Ok, thanks!

I've got the schematic, and it does list the parts pretty clearly as you described them, which is good, didn't realize it was that easy. I could just try to take each one out and see what that does, but could I do any damage that way, and how would I know which one was bad if I don't see any broken ...

Great condition, recently repaired Multimoog, now works and sounds great. I've owned it for nearly 20 years, but now got a Source, which is a bit more flexible, but I'm still real unhappy to sell the Multi, which is slightly fatter (the oscillators drift a little more unpredictably than the Source ...

hi, thanks so much! since I'm really new at trying to fix anything, any way you could be a little more specific on how to get this up and running again, like how I would locate the defective part inside the board, source a replacement, etc? many thanks!

Hello, I am having exactly the same problem as the OP described. There was a saw wave in VCO 1, now there isn't. When I press the VCO 1 pulse button I get pulse, tri I get tri, but when I hit saw, it stays tri. Any ideas on what to do? This sounds like an easy fix, but I don't know how. Love the ...

Hello All. So my wonderful multimoog sounds, well, dirty, like there's AM or FM going on somewhere that's producing a low level buzz on both oscillators. It went from sounding smooth and creamy to like its over a crappy set of speakers. Slightly buzzy, dirty sound, and not in a good way.

Any ideas ...
