God is only a prayer away, and a couple hundred volts is all it takes to meet Him. Only At the very minimum, consider installing fixed bias in the amplifier. Two mods are presented, one with a regulated bias source and slightly reduced plate voltage, and one with an unregulated bias source. Although a couple of the images show the absence of the power supply choke, it was reinstalled before use. Three amps after painting, one for center channel.
