My riddle of the humming V5 socket Sherwood has lead to some interesting findings.
In the V5 socket this happens.
If I put in an OLD tube - any old tube - there is NO hum.
If I put in a NEW tube - any new tube - it hums.
If I put in a NEW tube: the MORE hours it has on it - the LESS it hums.
There is a direct relationship to the number of hours on the tube to the loudness of the hum.
I've been burning in several GoldLion B759 tubes. It seems that at about 200-300 hours - that seems to be the NO hum point.
Any scientific reasons?
