You probably won't see much difference on 10m - the suppressor should be
adding 1-3 ohms in series between the plate and tune C. The circuit
impedance is typ. 2-4k, so the power loss is a few tenths of a percent.
To me a measure of 'goodness' of a suppressor is the ratio of series
resistance it adds between the plate and tune-C at 30MHz and 100MHz.
I've just spent an idle hour making and measuring a number of
suppressors to give different values of R at 30MHz, using copper and
nichrome for the inductor part. In every case so far, copper gives
