That looks suspicous, maybe a heater-cathode short either inside the tube, or in the tube socket? With the power off, take an ohmmeter measurement between the cathode pin and the chassis ground. Also check resistors R98 and R99, the parallel pair should measure 110 ohms. A short on pin 3 could overheat them and blow them up.
