I am in Winnipeg Canada and am interested in your Synth as well...if you are getting rid of it I have one in need of repairs just as you do ...tell me more about yours....also Tom,?You may have a co buyer for a CS60... as?a CS60 popped up on Ebay 2 days ago for 700 dollars US....

Subject: Rép. : [yamahacs80] New to the group, but maybe not to some Hi Tom, I'm sorry i can't help you cause I'm no tech at all. Just a keyboard player who happens to own one of these monsters. And I'm seriously considering the option of getting rid of it since I'm not using it anymore these days. So if any of you out there want more info on this just write me through the group. I'll be glad to tell you about. Fran?ois P.S.

Date: mardi 3 Mars 2009, 20 h 04 Hello, I hate joining a group just to get a question answered or problem solved, so I'll try to stick around and be as helpful as I can be. In addition to the other old synths and effetcs I've accumulated, I have a CS-80 here that I'm repairing. It's got a weird problem and I wonder if anyone has seen this before. It plays normally as long as I don't pres any keys in the topmost octave. I popped the hood and traced it down to the YM26700 D/A converter on the KAS board. Well, at least I think that's the problem. Here's what I measured: pins 19-30 are getting the correct voltages for each key in theoctave, pins 13-18 have the correct voltages for the octaves (0.125 through 4), pins 5-8 are reacting correcting for each key in the octave, pins 9-11 are reacting correctly to indicate the octaves, pins 31-38 (channels 1-8) output the correct voltages up and down the keyboard until I press keys in the upper octave. If I press a key up there, the voltage reading drops into the negative (i.e. -2.5v, 3.5v, etc). Could there be anything outside the 26700 causing this behavior? If not, are there any sources for a YM26700? If not, who wants to buy a CS50 or 60 with me for parts? Oh - I do happen to have a handful of lever switches, keys (white and black), some panel buttons w. bulbs, and the entire 4-bank 'memory' board that fits under the flip top panel, so I'm not coming here completely empty handed... thanks, Tom Offrez un compte Flickr Pro à vos amis et à votre famille.
