Hi All
Again - thanks all for your help so far.
I've attempted to take some scope photos today and I don't know if these will be helpful (the appear ok to me with regard to 1/2 wave rectification as they are recorded for one lead to ground). These are as follows:
- Just the valve heater (one side) to the CT (no valves installed)
- Pin 5 of V3 with EZ81 installed
- Pin 5 of V3 with EZ81, 2 x EL84 and V3 (ECC83)
The last photo I am not sure about which is the heater wiring (which has NOT been altered). It does appear that there is heater wire going to pin 1 of V3 - aren't the heater connections pins 4 & 5 of EEC83 or am I completely wrong here??
Best Regards
Rob
