I need a untampered with PC402A and PC402B boards for a K200A series head. This is the double selective boost and harmonic clipper board. Does anybody know if a B series boost/clipper pc board could be wired up to an A series? If so, that could work too. These boards on my A3 were toasted before I bought it due to a soldering iron in the wrong hands. All effects work through the left channel only on A heads and that channels power is routed through the effects board.

Kustom Rules!

I have never seen the inside of a A model head, But if it is set up like a B head wire wise it would be like this.
#1
preamp positive and negative power supply of + 8 volts and -8 volts feed to each preamp board.( red and green wires in B model)
#2
A blue wire bringing the output signal for each preamp to the driver board.
If your amp is like this, than YES you can use the B SERISE boards in your A model if the control spacing holes on the front panel are the same.
