Default Re: Decca PC/ML Console radio of 1939 find

Hello to all looking,
I have finally got the set running after replacing 10 capacitors, the O/P Tx and rewinding the field coil and replacing a rather danerous mains lead. The set works well but I have a low level mains hum from the 10" speaker which is a little annoying. I reversed the hum bucking coil which did make it a lot better but its not quite good enough. Does anyone have any suggestions on how best to improve it? I am minded to add a few uF extra to C19 (8uF) but don't want to overload the R2 rectifier. Its also a real pain adding value due to stripping it all out again, especially that autotuner pack! The set can be seen running at https://www.***********/photos/atlant...7706885637031/
