Many years ago I got one of his kits for my single 4-1000A amp and the
suppressor went with a bang. I went to normal suppressor. The point is
to simply introduce loss, lower the Q, of VHF parasitic resonances that
can exist in the plate circuit of the amplifier.

Sorry, I met him over internet right after his write-up for AR Handbook was
rejected and that was a long time ago. I brought up his name here once
before and got slapped for it, sorry, I should know by now. I owe cup of
coffee to all. Hopefully we will meet some day.
I still have his suppressor package for two 4-1000A 's to be installed.
Without bringing his name out again, can someone warn me about using it?
I installed his suppressor package on my friend's Henry 2K. It lasted few
years, but his plate transformer croaked recently, I wonder if the
suppressor had anything to do with that.
