>The heater voltage is 2 volts. The plate voltages are a little lower.
Confused. The plate voltage is lower that 2v??
> The bias voltage -7 of the #30 tube changes when I turn the volume control.
The volume control in this set is connected to the input of the mixer and the -7v line goes the ground thru a resistor as the volume is adjusted. Most sets the volume control is connected to the det and 1st audio stage. .
>I'm somewhat confused on the alignment procedure.
Well let's start off easy. Set your generator for produce a modulated signal @ 460kc. Connect the hot lead to the grid cap of the 1A6. At this point you should the tone coming from the set. You may have to tune the generator a little to get the max signal. Tuning the dial on the radio will not effect this adjustment. Adjust trimmers 16,18,19 and 21. This completes the IF alignment.

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.

Now I think I've got!
