Forgot to mention that the 'buzzing' only starts after the relay
closes - so more evidence that it's either the 80/450's in the PS, or
possibly a problem somewhere around the voltage divider/0A2/6DR7
portion of the circuit that is fed from the 600V terminal in the amp.

Not possible that it is the relay itself that is mechanically buzzing
perhaps?

The relay itself isn't making any noise; it did 'buzz' a little
before the fuse blew prior to fixing that problem, but it's a 60hz
noise in the speaker now. Suspect the PS since most everything in the
amp that could leak 60hz has been replaced.
