Have you seen and touched this amplifier?

I'd at least lift the lid, unscrew the RF section cover (containing the tube
and plate tank) and have a look in there to see if there's any evidence of
what caused the power supply failure!  Possibly the tube became an expensive
fuse-?

And "power supply damage" can be minor, like blown rectifiers, or major,
like a blown transformer and/or choke.  I'd want more detail on this before
trying to evaluate the amp's worth.

I didn't know any 4K's used pentodes.
