50C5 valve with a strange fault.
This would be a simple question but is likely to end up long and winded, what a surprise!
I'm nearing completion on an American GE set but have come across an issue with the above output valve when running it on the valve tester.
The first fault I found was that pins 2 & 5 (both internally connected to G1) seem to be operating the heater, as is pin 4 which is the correct pin for the heater, is this normal?
The other thing I couldn't help noticing was the fact that there appears to be some form of electrical leakage between the anode and cathode, this would usually be a bad sign at the best of times.
Would this render the valve scrap?
I don't fancy the idea of having 50v ac as opposed to the usual negative voltage driving the grid!
Any help/advice greatfully appreciated.
Regards, Rick.
