Wonder if any body can explain the odd hum I get with a modified Dynaco FM-3. It always happens when the cage is screwed on in it's proper position. If I undo all the screws and move the cage about a bit it will stop when in certain place's. If the cage is taken off all together again no hum. Just seems very fussy with position of cage? I have tried earthing the cage with no success.
Any thoughts about how to sort out problem as I would prefer the cage screwed on. I have young kids with curious fingers.
Thanks

Hi captaink
Might be the screws when screwed in are touching any part of the circuit?
