What in the heck does it mean?

Too hot, in the case of the Kenwood R-1000, is that the power supply
has to be resoldered about every 5-10 years because they're 1) running
too much current through too small connector pins, and 2) used a single
sided PC board and the expansion/contraction of the power transistor
leads breaks the solder joints to the board pads.

In some ways this 25+ year old radio is an engineering feat. It has a
single sided board full of 74S (!) TTL and it doesn't seem to interfere
with itself, or much of anything else, but the power supply section is
not one of it's better points.

And it sounds like they didn't improve those parts much in the years
between that and the R-5000.
