Hi Terry
That is exactly what I have done. The way it has been done on the circuit is very confusing, and I believe may even be wrong.
Can you reconcile the official voltages with what I have marked up on this working ITT Colt chassis, which is an identical chassis to the R135 (apart from the dial mounting method)
Schematic showing voltages from a working circuit are marked in green. All measured with +ve probe connected to the +ve ground.
I will start to compare them with the non working circuit when my back is feeling less tired.
thanks
Mike
p.s. I started to check some of the resistors in the R135 and most of the ones I checked are high. e.g. R303 was 950 ohms
