T he heater voltage is 2 volts. The plate voltages are a little lower.   The bias voltage -7 of the #30 tube changes when I turn the volume control.
I'm somewhat confused on the alignment procedure. 
Thanks for all the help.

Trying to align a dead radio is not the way to troubleshoot, likely only create additional issues. Proper alignment relies on radio producing a signal that can be measured at speaker.
