Hi
I have an R209 mk2 that was converted to mains by a previous owner. I will have to open it up to remind myself exactly how it was done. From memory it was an appropriate HV transformer with a regulated supply for the filaments.

It works well on AM but the CW tone sounds more like a buzzer and there is some drift in that mode. Not sure if it is the BFO or VFO.

I have considered converting it back to 12V but i guess the vibrator transformer is unobtainable and I don't have an original to get rewound.
