  Took some voltage readings on the rectifier tube today and stopped after getting these readings.
pin 8 & 2 307 volts DC schem. calls for 375V

pin 4 & 6 284 volts AC Schem has no volt rating on 2 & 4 pin. this is the secondary of the switch side of transformer.
 
  I don't know if the wire recorder / amplifier has to be in the circuit or not for correct volt readings. On schematic you see that amplifier has its own rectifier. I'm concerned about the high AC readings and what I should check.

  Here is the schematic of the radio and amplifier kind of blurry but you can see the pin out of the 5U4G tube.
Any ideas what I should check next? Thanks
