Nick, if the amount the pointer is off-scale is the same on all bands (ie 6mm on all bands) take a look inside the cabinet where the top of the pointer is...
Hi, A few weeks ago I acquired a 940 and since then I've been ironing out various faults, (those that I've found so far). I've just discovered that the HT...
Greetings all, I have recently aquired a 770R in reasonable condition and the restoration project is progressing quite nicely. The set unfortunately has the...
I think you will find that the coils on offer on Ebay are for the 770U not the 770R. Am pretty sure of it having spent three months fiddling with these colis...
Howdy All, Thanks for the info.. Graeme, I have to agree with Mike. I checked out the lot on offer from Ebay and concur that they are for a 770U. I have done a...

Hello Graeme, many thanks for replying to my post. Yes, I have read the 'Cascode Catastrophe' article and I have replaced all the V1 stage passive components...
Hello Gerry, I've spoken to Bill Cooke (who designed the 940) and he says the mains tranny is good for at least a 15% overload, and that the set proved very...
Graham, for your info, Mike Hi Gerry I re-measured the volts across R8 and R15 as you requested and also included V9 for completion. I also measured everything...
Many thanks Graeme. Good advice from Bill regarding letting the fault develop, though my main concern is damaging the mains transformer (exact replacements...
Graeme, Another thought: by using the voltage info on the circuit diagram (HT1 at 240v, 'cold' end of R8 at 165v) and the resistance values, the current draw...
OK Gerry, yes, it does measure up more like, doesn't it? Bill kept repeating to me to tell you not to worry. He said he built plenty of safety margin into...
Hello I have just bought a 770R mkII /12 that I´m going to restore. The main problem just now is that I need a manual for this receiver. Is there anybody who...
