I have now replaced every resistor in the radio. So #38, 25, 37 is correct, and I disconnected one end of 17. The voltage from the plate of the XXL tube is 44 Volts when measured to the chassis, and 64 V when measured to the negative end of #60. The voltage did not increase when I disconnected one end of #17. Still only static for this radio.
