Trying to diagnose the weak distored audio problem I have with the 500,
I see where the clipper stage (6AL5) was removed and replaced with an
additional audio amplifier stage using a 6C4. I also see a small perf
board installed using a circuit made up of a resistor, three diodes and
a SK3021 NPN high power transistor. Wondering if this is some kind of
solid state clipper?? Anyone familar with these mods? I believe the
extra audio stage mod is a WA1HLR design. In his article he recommends
removing the clipper stage and replacing it with another audio stage
using a 6C4 or 6AT6. He does not suggest a clipper stage.
