I have the above transformer with a short between pin 9 & 10, the main primary winding and "yoke" winding.

It isn't the boost capacitor. If only!!

Is it practical to rewind the "yoke" winding only ie after pin 9 of the TX.

If so, how many turns are likely

Hi Chris, a picture of the beast might help.
Provided that the EHT overwind can be removed or is on another "leg" of the transformer, it should be possible to carefully reverse engineer the primary windings

Have fun
