[crackle]

Here is the power supply shelf from the KB 540. It is electrically identical to what I need to make for the 428, but the one I need to make will be 2 cm wider as the cabinet is slightly bigger.

It would be nice if I could find a fuse holder/voltage selector like the one in the photo, a transformer similar to the one seen with rounded corners and screen cover, 265v HT and 2 x 4v heater windings with spare room to wind on a few turns to boost one heater winding to 13v, and also a 4 pin paxolin type valve socket.
I will post an advert in the wanted section..

Thanks
Mike
