Hey Mike,
I do the rough calculation by multiplying the # of tube not counting the OP or rectifier X 5 (ma) If and tube has more than 1 section + 5 more ma per, diodes don't count. OP= 20ma. So 7 tubes X 5ma + 20= 55ma + a little for good luck=60ma.
Then I look up the tube specs to see if the rectifier can handle the current load. 84 is good for 60ma.
When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
