A while back I started rebuilding a Dunlap Clarke Amplifier. This is an update to the rebuild project. I stripped the cabinet almost completely bare, then cut holes in the sided for new heat sinks. Next I drilled holes for the power transformer.
Next I installed the heat sinks with the new circuit board and wired everything up. The new power transformer is 50 volt center tapped at 8 amps.
So far all I have done is a hum test. I connected speakers and tapped the input screws to produce a loud hum. Next is to wire up the input jacks and level controls.
