Sounds like the kind of problem that develops with table top ham gear
that's crammed into a too small cabinet.

Several years ago a friend of mine and I got into a Command amp that a
mutual friend brought to us for repair.  It was the model that had a
single 3cx800 on HF.  It turned out to be okay (some kind of operator
error) but we spent enough time on it to take in how it was made, with
the inaccessibility of the power supply area (caps and diodes).  That
part of the amp sat in a shield, underneath the band switch and output
network, and had no access panel on the underside of the cabinet.
When we got it back together I told the owner to unload it ASAP
because if a diode or filter cap ever crapped out, the bench time
needed to get to the power supply and reassemble would make the repair
four or five times more expensive than it needed to be.
