OK here's an idea:
power down, unplug,
In the 7C7 socket measure Ohms between the plate pin and the chassis. See if the short is there.
pull out, measure again. See if it disappears.
If no short, put the tube back in, measure again, see if the short appears. If does change the tube.
If short is still with the tube pulled, look at the socket. Or around. Or in the coil.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
