When setting bias, set power supply current limit to 1 or 2 A. That will prevent blown finals.

Without transistors check if you get a smooth 0-5V variation with presets.

My finals now blow when attempting to set the bias, I¡¯m concerned I may have damaged something else as well. Is there anything in particular I should be checking?
