Hi,I covered this beautifully eight years ago - after about 30 years of A-Bing this on DHT amplifiers, almost always Class A1.
Boy, did I make enemies. Here goes, to remind you all:
DCR of half the high voltage secondary winding (if a center tap) or entire secondary( if a non center tap) of a typical (audio output tube) amplifier :
" HIGH FIDELITY" is 20 Ohms or less DCR.
" ULTRA HIGH FIDELITY" is 10 Ohms or less DCR.
And this hasn't changed ONE IOTA.
Cheers,
Jeff Medwin
