We don't have a vintage radio thread to answer, so needs must. The 3K resistor (R19 in the manufacturers data) is the heater dropper for mains operation. You should have 85v at one end and 6.7 at the other, on mains operation with the mains voltage selector on the right tapping. If so, the resistor is OK.
