The zener fixed the problem. Now if I could find some 70-503-41 replacement pots. I have two with broken shafts.

I am pretty sure I found the trouble. One of the two 16v zeners was running at only 7 volts. The other one was fine. I will know for sure when I get a replacement zener. Thanks to all.

Does anyone have a schematic for a Crate PA-B6350 (6-channel mixer) or PA-B8350 (8-channel). Power amp section works fine, but -15vdc on preamp board is only -7v. The +15vdc is fine. I have pulled all the opamps, but still no -15vdc.
