philco 40-170CS overheating resister
#13

John

Coil shorted will not cause that. Coil is a few ohms in the first place, and it is in series with that 1,000 ohm resistor.
Shorting this 10-50 ohm resistor equivalent which coil is with 1000 ohm still there will barely affect anything.

If it were just the 1000 ohm resistor I'd say this is the #13 cap is shorted. But with the coil smoking too this has to be something after the coil.
Potentially the short is between Primary and Secondary of that coil, but then I am not sure what is there after it.

Also 7C7 shows some sort of screen grounded; check for short in the socket pins.

Last thought: the coil is shorted to the case that is grounded. Unlikely but is worth of checking.

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.
