Alas I don't have a new 'original' replacement R209 vibrator-transformer to hand! And I guess such a beast is as rare as Unicorn-droppings.

A used replacement - I'd be deeply concerned that it might soon go the same way as the failed one I need to replace (I'm always wary of using used parts). I have a philosophy of 'continuous improvement' - a repaired device should work better/be more-reliable than the original.
My mains-transformers approach seems to be working well as a bench lash-up; there's a good 115VDC available and the voltage-stabiliser ignites nicely. There's also none of the old annoying roughness of the BFO-note when listening to CW/SSB. Now to package it up and fit it back into the chassis.

Oh, and I need to source a suitable mains-connector. The R209Mk3 - which was mains/battery - appears to use a 6-pin aluminium shell Plessey-type connector.
