Hi Adam,
Thanks for file. The diagram helps a lot as it is perfectly clear, and I can see the connections to the 9-pin plug/socket.
I will phone you tomorrow (12th), what would be the best time? The reason I was initially looking for DC filament volts was simply the fact that I could just about make out LT+ and LT- on the diagram and that led me off on the wrong track! In the main unit, everything seems to be in 1st class condition. Even the dripping wax capacitor (.05uF) tests OK. I will probably check the ceramic resistors as well, as they can wander way off value over the years, 79 in this case, as the checking date, signed by the engineer is 26th October, 1937!
