It works! Ed's transformer works perfectly. Two TCC waxies needed replacing, the coupling capacitor from the anode of the HL23DD triode to the primary of the push-pull driver transformer and the screen grid decoupler of the TP25 frequency changer and the VP23 IF amplifier.
These radios with the 2 volt Mazda Octal valves can perform almost as good as a mains radio.
Still a few more jobs to do, the short waveband is dead and of course that rusty chassis needed repainting.
