Subject: KAS / YM26600 question

From: "tmoravan" <moravanskyt@...>

OK - time to yell for help.

Cleaning up a CS-80, and there's no voices sounding when playing a key. Started debugging at the KAS. All power looks good, note values are registering. Nothing appearing on the trigger outputs. Going backwards, the U1 -> U5 are mostly pegged at 8.48v and do not change no matter where on the keyboard I press.

Is this a dead YM26600, or is there something else causing this?

While I'm here, what should the clock input on pin 2 really look like? I'm not really seeing a stable square wave kind of oscillation there.

thanks
