Earth to LeGrace: You have a severe, significant problem *somewhere* within your system. The shock is a gentle warning of same - the next warning may not be as gentle. I really do not want to be snarky - but neither do I wish your SO to find you in some state of disorder, possibly permanent - or someone else in your household.
You need to do some significant, systematic and complete diagnostics as to *why* you are getting hum - I can think of half-a-dozen. And each one of those is potentially fatal.
a) Shorted cap.
b) Shorted transformer primary or secondary - shorting to the frame.
c) Pinched wire.
e) Cap shorting to case.
f) Fudged connection where none should be.
g Any other suggestions? I am not going towards tubes as so many have been tried... But that is yet a few more possibilities.
Do not pass go, do not collect $200 - go directly to your VOM. On BOTH AC & DC volts, measure from the chassis to a good ground from each component you have, independently and collectively. If you are getting *ANYTHING* more than a few MV, you have a problem. Isolate where that problem is and both your shock potential and your hum WILL go away. This is a most basic life-safety issue
- having nothing to do with things Dynaco, VTA amps, tubes, nor anything else. FIX IT! If you cannot, or choose not, or will not, do not permit any living creature but yourself any contact with your system under any conditions. And think long and hard before touching it yourself.
