Marconi TF1374 Crystal calibrator circuit wanted

Post by G8GQS » Mon Jun 18, 2018 8:26 pm

I have one of these, made in about 1961. its quite nice and has outputs at 10,1, 100KHz & 10 Khz.

Alas like a lot of things it needs fixing, so if anyone can provide a circuit or even better a handbook that would help a lot.

There is a bit about it here
