Since we are remote the only sensible thing to do is disconnect C61 and then keep disconnecxting things one by one until you see what it is there from the things wired together at that R60 point that is connected to GND.

Once you figured this out then we can proceed. Guessing won't help much. Anythings possible, even shorted to the chassis transformer, though it is not likely.

Also see if you have old rubbed through wires touching chassis etc. BTW C17 may be shorted for that same reason. Or if wiring is new - if something is touching the chassis. You have to be diligent.

The only thing I know for a fact is that finding shorts in large systems like an old radio is extremely easy, if it is a non-intermittent reliable short. There are only sop many things that can short.
