Ok lets check the dc voltage at terminal 6 on the power transformer.With - probe to the chassis and + to the terminal should see about -50vdc. If you do your audio driver transformer is suspect #21. To check it with the set off measure the resistance from terminal 6 to pin 3 of each 71A. Should see a fairly low resistance like less than 1K. If your seeing anything up in the 10's or 100's of K transformer is kaput! AES has a suitable replacement for abt $15. https://www.tubesandmore.com/products/tr...tage-10-ma

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.
