Yeah, I knew that I needed to run them about .6V or so, but what specifically should I be using for diodes and resistors?

Currently it runs 1N5820 diodes which drop .35V. Those are ran in series with a 10 ohm, 20W resistor. This setup is run on each set of transistors for a total of 3 sets.

I tried 1N5401 diodes, which drop .7V with the same 10 ohm 20W resistors, and promptly cooked all 4 finals. The drivers were fine and didn't sustain any damage. Soooo... it's back to the drawing board. What would I need to do to effectively drop the voltage down to .6V or so?

I am thinking of bypassing the driver section and running it as a straight 4.

Thanks for all the info so far

~Cheers~
