My TS-690 is a TS-450 with Six Meters. Several years ago a problem
turned out to be caused by a leaking electrolytic capacitor. The
leakage corroded a circuit trace, opening the circuit.

My old TS-50 has numerous bad electrolytic capacitors. I gave up trying
to fix it. (I was doing more harm than good!)

Kenwood seems to have used some poor electrolytic capacitors, and they
are causing problems in their old age.

FWIW my 20yr old IC706mk2 suffered failure of an (leaking) electrolytic
capacitor a few years ago, and corroded part of the track to which it
was connected.
