Hi all, I've been browsing the archives to no avail. I would like to have my tech go through my 50 and have some minor issues fixed, like unsollicited portamento on some voices, pitch

This is pretty loud. And as I said, it seems to be eminating from the PSU... As in you can hear the power transistor on the -15Vrail whining away, if you've got the audio out disconnected. But it

I recently read about a modification that was done by Kent Spong which involved re-routing the cable loom because it would produce some kind of high-pitched whine. Maybe Kent could elaborate on

Hi Tim Thanks for the advice. Moving cards might be a way forward. Will give it a go. yamahacs80@...> wrote:

Hi Bob?You bought a part from me a while back....80% chance there's nothing wrong with the supply at all.?I assume you've thoroughly investigated visual possibilities on the 2 offending voice cards,

OK... so I'm going to build a power soak to try and pin this down. ie. whether it is actually the PSU or if it's something elsewhere causing the issue. Measuring about 0.6A on the +15V, and 0.65A on

Hello Mike, Actually i've been reading about -6.5v/+8.5v (1/0) process almost everywhere in the manuals, and precisely this is what pushed me to really check the KAS LSI's, when i realized my

Thank you Crow, actually i did mention that one in my sources for collecting infos, but indeed i didnt go thru all the detailed explanations about the LSI's functions...It is true that i opted for a

What is your objective here?? I've had a few of them fail on me.? The most common symptom of failure is the top octave not responding.? -Mikehttp://borishelectronics.com

There is a complete analysis of the custom chips in the Yamaha CS Servicing Guide. I used this book to work out IG series equivalent circuits a dozen or so years back. It covers the YM parts too.

Hello CS80 users, Probably as most CS80 owners, i am aware that the most critical parts in the beast are the 2 main LSI's (YM26600&Ym26700), as their failure could quickly become problematic,
