In Topic: Strange diodes on D75 main board

10 January 2015 - 08:35 AM

I pulled those two diodes and cleaned up the excess solder. The amp seems to be working just fine without them. They were definitely on the outputs of the LM339 comparator that drives the IOC LEDs, limiting their excursion to no lower than -10V. I can't see how they could go lower since that IC is powered by +/- 10V.
