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.

Lifting the plate lead eliminates any issues on the tube side of the plate lead because it removes the the RF tube and socket, etc from the equation and leaves you only with coil, coil leads, internal shorts to ground, shorts between pri and sec, solder blobs etc. It's the easiest way to eliminate the tube and everything ahead of it in one action.
