The FM 6BE6 measures 235 volts on the plate, pin 5. You may need one of the Pomona adapters to measure voltage on this tube since it may be hard to reach in the tuner can.

I am a little confused about this measurement. The paperwork shows the 6BE6 for the FM on the front of the chassis and the AM on the rear of the chassis. However, I get about 295VDC on pin 5 for both of these tubes, but only on the front(FM?) tube when I have the switch to AM and on the rear (AM?) tube when I have the switch to FM.
Can someone confirm which tube is which?
Thanks!
