Suppressors are usually tube and layout/construction dependent for the inductor part.

Look at commercial and good HB ham amps that have the tube you want to use and go from there.

Having a quality brand of GDO helps a lot as an economical tool..

Thanks Carl,
I just have to figure out what the factory design should be. I will definitely use ceramic resistor. Any suggested lead to better suppressor setup?
Values, arrangement? Thanks,
Karel, VA3KO

Stick to factory designs, they work fine for decades without problems.
The Ohmite OY series of ceramic resistors do well in place of out of tolerance carbon composition.

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.

Quoting Karel <kebenstr@bmts.com>:

Hardy,
yes I made myself a Hi-pot tester as well. I forgot the specs, but I believe I can go up to 20 kV. (It may be one of Richard Measures designs).
