2. Voice 3 on Channel 2 is outputting only noise instead of a saw/square. Sine is working

well.

when i had this problem, it was a bad VCO chip(153?). sine and noise are not generated there. easiest way to tell is to swap the chip out for a working voice-be careful! the legs on those types of chips are easy to bend putting them in and out of sockets. good luck-rj
