I right clicked on the thumbnail and selected copy image, then pasted it into MS Paint and blew it up.
No way of reading values of course but it should be possible to redraw the actual circuit accurately.
There is one oddity - the cathode of V2 is connected to the usual resistor/capacitor parallel network but there is something between the earthy end and the chassis. It looks like a switch, which is ridiculous.
A visual inspection will be needed to establish exactly what is there.
It is interesting that, if you scroll down in the window of the RM entry that it also includes Trader 528 but the all valve one is headed just TRADER SERVICE SHEET without a number - or so I thought, but looking again it appears to say SHEETS, which doesn't make sense - but SHEET5 would ...
