Circuit Diagram WeyRad SGM1 - UK Vintage Radio Repair and Restoration Discussion Forum

Geoff 555 · 24th May 2011, 12:37 pm

Hi all. It's a model SGN1 and if anyone has a circuit diagram I would love a copy please. It has been got at, for example a resister added to the heater chain to lower the volts to 3.2 V. this with the usual 6.3 V heaters.

Only 2 valves employed EF91 and 6C4. Metal rectifier.
Thank you.
Cheers.
Geoff.

Hello folks

I believe Geoff555 was looking for the circuit diagram for the WeyRad SGM1 signal generator. I have one of these sig gens that I purchased from a member of the forum and have drawn out the diagram of this instrument. So for you Geoff and others here it is in a PDF format.

Regards

Ken
