Check the wiring to the 6J8 tube socket. There should only be two connections to pin 6. One will be the 4.7K resistor 29 and the other should be the 250 pf cap 22 going to the push button switch. If you have any additional connections there is a miswiring problem.
With the 6J8 out of its socket, the only other part connected is the 250 pf cap and that should not draw any current to overheat the resistor. You must have a short in the associated wiring or something is miswired.
