I've run into a couple 84's that hum when everything checks good and the problem turned out to be a bad ground on both of them.

If memory serves me correctly, there is a ground lug attached to the 42 tube through one of the tube socket's mounting rivets. The mechanical connection corrodes and you have hum.

Hope this helps

Ed
