did you disconnect everything frmo the secondary side and fire up the
primary side and see if the resistor still get hot.

if not, you have a fault on one of the secondaries, reconnect them one
by one.

if it still gets hot, you have a fault on the pri side or a bad xformer
perhaps in the form of a shorted winding. Use yopur 2v drive on the pri
to try to isolate a shorted winding,,,how??? I'm not sure. See if
there is any winding that when you intentionsally short it, nothing much
happens.

Yes, I'm pretty much on the same page as you with those suggestions. I've
sorted through about 500 caps today and not one of them was a 560pF!!
Could not believe it but still have a couple of thousand or so left so
maybe there's still hope.
I'm using an old valve HP sig gen for this purpose as it puts out a
healthy 75V p-p maximum thereby getting closer to the operational voltage
than a modern solid state one would be capable of.
Anyway, I'll report back in a day or so....
