Thank you to those who responded to my question about one of the channels not working.
Having dismantled and rebuilt the tone switch unit (not for the faint hearted!!), it still didn't work. Then I remembered that the ECC83 has TWO anodes - I'd only tested the voltage on the one nearest the output valve. Result? No volts! Cause? An open circuit 180k resistor in the anode feed. Sorted......
Moral of story - check ALL valve voltages and remember that valves which are effectively two valves in one have two of everything (almost!)!!
Won't get fooled again!!!
