This rather small transformer has broken down to the tertiary winding and, when that is disconnected, the transformer has a shorted turn.

Thanks, don't bother, I adapted a NOS Rola TV458 late 50s replacement type I'd had for years. Had to add a couple of windings but it's now working.

I put the story of the resto of the P4 up here, mainly because of the RCA influence in AWA's circuit designs.
