I want to say thanks for all the reply's I got to my problem in my SB-220
and mostly to Gary K5JWK who pointed me in the right direction. I had
completely stripped down the amp to clean the chassis because it was down
right filthy from a filament transformer meltdown sometime in it's past and
sitting in the rain forest take my word for it was filthy. When I
reassembled it I had inadvertently installed the tank band 180 degrees out
so that was where the problem was. I can now say it is working just fine now
and doing better than I thought it would.
Here is the power output I get into a dummy load and 100W drive readings
from a Palstar PM2000AM Peak reading meter.
