Hmm, I can't see the BC505 in the attic. I'm sure that's where it is. So there will be a day or three delay...
I've a Decca TP60, which seems similar to the BC505 for AGC and transistors, but I don't see it either. It and BC505 were side by side on a shelf. I found a Decca TT33, which actually is similar to the BC505 anyway.
I can't imagine what X1 diode is for, unless to boost the IF voltage?
