followup: Carver PM-1.5a amp
 

First time of meeting this triac drive rather than protection concept
Upping to 90 percent mains the current draw drops from the 0.5 amp of 80
percent maions to .2amp approx and then at 100 percent approx .25 amps, now
to test under heavy load

followup: Carver PM-1.5a amp
 

What is the prognosis for PAT/insulation testing of these "magnetic field"
amps, knocking out diac/triac etc ? with 3.9M, R8, between ground and one
side of the mains transformer. Triac protection ccts are isolated from
ground, IIRC, where used in amps.
