Documentation of repair, settings and testing of Peavey 6505+ head. I could not get the power amplifier to meet its specs until I corrected the filament voltage issue. Apparently, the PC board runs are so thin that the drop across the paths adds up to 0.6 volts by the time it gets to the PC board with the 6L6's. Also, front control settings are critical for providing maximum output with desirable overdrive and effects. Hope this helps.
