Well, start tracing wher the short is.
Were you measuring towards the GND or towards the minusses of C45/C46?
Possible places (disconnect and measure):
1. Output transformer (not sure how), it does not touch GND
2. Socket of 42 tube, SG pin
3. Socket of 78, P pin (doubt it, you'd have some open coil 23)
4. C20 (0.01uF, in the sch shown near R22 and R19)
5. 6A7, P pin (same as before, doubt it.)
6. Field coil (doubt it, but who knows.)
Just go by the wire and trace it.
Again, it should be nit a short but 260 ohms or so if measured to the GND.
