[Amps] Grounded B+ amplifier

[R.Measures]

•  The floating cathode/DC grounded anode amplifiers that I have heard 
about had tank circulating current had a water-cooled tube, vacuum-caps 
and a water-cooled inductor.   Reducing the L of the anode choke 
obviously solves helps to resolve the resonance problem, but perhaps 
there is some advantage in eliminating the DC-blocker cap at such power 
levels by going to the DC-grounded anode configuration?

•  PVC does not have a low dissipation-factor.  ABS and G10 are about the 
best.
