<Steve, this sounds like an output padder C that has lost ESR and heats up

## He did not say what band he tested on. Any loading cap padder would be on
the 160 + 80m bands.
He might want to re-run the tests on 40 + 20m..... if its fine on 40-10m,
then its 99 % likely to be a padder
on the lower bands.
