Hello,

Thanks for the compliment! No fluorescent lamps nearby.

I have shortened the leads on C33 and the buzz is less. I might try shortening a few other similar leads on capacitors that I fitted, but they are not near the 10C1 valve so perhaps irrelevant?

There are a few trimmer capacitors in the MW/LW circuits, one at least has been fiddled with (by me! - it was very loose and I think I disturbed it accidentally). Could setting these up with a signal generator help? (I am going to steer well clear of the IFT cores.)
