that is not in the 169 chassis, it was in earlier chassis like the 167, I
think, all of the chassis that used a SCR as the chopper. The trim pot on a
169 is adjustable.

from my local distributer only sent an IC. I remember other repairs made in
the other chopper circuits included a preset trimpot that was matched for
the new IC. My secondary voltage's do come up but quickly go down because of
overvoltage in the secondary. Neil
