39-6 power tranny question
#4

Just measure the ac voltage from the each of the rectifier plate to chassis gnd or the power transformer center tap w/ the rectifier tube out. We're looking the see if the two voltages are fairly equal. Like what you did with the ohm measurement from ct to each end just we're looking at voltage not resistance.

If the voltages are unequal by 10% or more it may indicate shorted turns in the hv winding. Same w/ transformer heating in a relatively short time.

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!
