Greeting,
My Crate has developed a drop in output that is thermal in nature. After approx 7min it rolls back to a minimal distorted volume. I'm assuming this is either the heat tracking device on the heatsink. Or perhaps a zener in the power supply. The schematic unfortunately is not readable. So I don't know the values involved. It has what looks like 2 large diodes. Plus what appears to be a single 5w zener. The print dosen't show either of the large ones. And shows 2 5w zeners for the +&-16v rails. The DSP appears to be fine unless related to this fault.
Any insight would be appreciated. I'll break it all out to where I can get the test gear on it soon.
Thx,
DD
