Hi Tony,
Just something else to look at, is any tie point to chassis. Occasionally, a rivet will develop resistance, even a couple of Ohms, and cause a buzz.
I have found two sets, one a Philco 84 IIRC, the other a Truetone that used a tube socket's rivet and a terminal lug for grounding. That rivet had a little over 2 Ohms. Jumping the connection, the buzz disappeared. Worth a try.
