For starters I would measure the voltage @ pin 2 and then pin 5 of the 19 W/the meter - connected to the chassis. Should see abt 135vdc. Measure the dc voltage @ pin 2 of the 30 tube, should see abt 135vdc. Check dc voltage @ pins 3 and 4 to chassis of the 19 tube, should see -3v. And pin 3 of the 30 tube should be -7vdc. If any of these voltage are very low or nonexistence then check the resistance of the associated transformer. All winding should be <1000 ohms.
This is presuming that the power supply is working/ connected properly.
Happy hunting!

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 it!
