Hi Brian, can you post a pic or details of "the small round transformer" you require. I have some that match that description so I'll have a look.
I've just been fixing and HMV 1508 "portable" radiogram. It used a mu metal cored AF transformer with balanced windings to couple the PU to the amp, and had dire warnings about not doing resistance checks on the windings for fear of magnetising the core.
I may have some radiometal lams if you need one winding.
