Hi all & Happy New Year! I just did the whole VCA adjustment a couple of says ago on a CS80 and also question the vr14 80mv. First, it doesn't say to desolder the M-Card output wire until the next

Hi. I'm doing the vca vr14 adjustment in the Mboard.Can let me know if in your CS80,the value was as described by the manual of 80mV or was it higher? I have calibrated it but the overall output

I have most of the IGxxxx voice chips in stock. :) Doug synthparts.com

I agree. I replaced all CMOS, caps, light bulbs, and Op-Amps in mine. Taking it apart and putting it back together again every time something breaks is too much stress for the CS80. -Mike

Nope - just the 4000 CMOS and the op-amps. That's my problem: I've been limiting my search to earth :)

When you say "full re-chip" David are you also including all the custom IG and YM chips? Where on earth would you find them all..? Cheers, TOM

I (and others) had given ideas as to what areas might be responsible. Since it's intermittent, might be time for some (careful) wiggling of wires and maybe some cold spray and/or heat gun to try and

-back in the late 70's they did claim these instruments fixed themselves...

Hi Kent, Thanks for your answer. I forgot to mention that the second instance this happened, it was very persisting. Had to bring someone to open it and take a look at it and then "miraculously" it

I experienced the same thing twice. No idea what is causing it. Kent

Hi there, I noticed the lower octave stopped working on my CS80 yesterday. All other keys, ribbon and knobs worked great. More specifically, the lowest C key on the left of the keyboard worked but

Hi Dave, I had a friend of mine who is cs80 savvy come by and take a look at it. He opened the case, took a look below the keys, to check and clean things up. He found a piece of glitter and we

Thanks - great to listen to! Although my mind quickly started hearing what ELP would have done with this in the '70s ala Fanfare :) Time to clean up wrapping paper. And, I got two CS80 (repair)

Many thanks for that - wonderful! Cheers, TOM

to all of you. It's been a while since I've been here. Made a little CS-80 track for Christmas: http://www.youtube.com/watch?v=IGuDccp0Oys

Hi, I realize that this is a Yamaha CS-80 group...but does anyone on here know where I could buy a Yamaha DX-1 memory/preset cartridge? Thank you, Mitchell Manger

This brings up my occasional reminder for those stuck with a bad voice card: it's pretty easy to put in a jumper on the KAS board and disconnect the audio output of the 2 M cards for voice 8. This

They will work - but they will drift at a different rate when the temerature changes... thus going slightly in and out of tune. I suppose it's a small price to pay if you can get an Osc chip at

This is a good point. Does anyone out there know if you can make the other numbers work. In other words is it possible to make a IG00153 '33' in a synth that has '11's'?
