Hi all..I have been shopping around for custom built Toroidal
transformers....My specs are for one rated 250 volts AC input
50CPS....Output 1100VAC @ 1 amp....1100va....I intend to use this unit
for voltage doubling to run a single GS-31B triode....I finally found an
Australian firm who can supply a Toroidal transformer rated at those
specs...170*80 (Diameter Hight)..
I am wondering what difference in efficiency there would be using the
Toroidal unit in place of an EI cored transformer voltage doubled such
as used in the Heathkit SB220 and other moderately rated amplifiers
