Hi Ray,
This is probably unrelated to your capacitor failure, but your
"big hulking linear supply" is underrated for the K3 unless you
run your K3 at less than full output power. The RS-20A might
be okay for SSB, but certainly not for RTTY or digital modes at
K3 full rated output power.
Does anyone know whether the antenna output not selected is shorted somewhere
near the output itself, or just left open while the selected output socket is
active? I haven't ever seen a schematic; the "Theory of Operation" in the
Manual is too oversimplified to answer the question; and
A wet finger and Ipana toothpaste was always my approach and solution.

It was about $24 with tax last summer, but I was able to pick it up, so
tax, but no shipping.

Back in the "olden days" of my Ham experience, licensed 1963, on a high
school students nearly non-existent budget, we used gentle pressure of a
clean soft bristled tooth brush and Ipana toothpaste. Sometimes several
applications were needed but it did work pretty well on the EICO,

In real life I'm an A (aircraft) mechanic, and this sort of scratching is

Very short unless that was a design goal! It’s all about temperature. Operate
an 85c electrolytic near 85c and it’s not going to be around long.

I believe the answer to be yes. It would overwrite the parameters, so any
problems in the saved configuration would be restored. Of course, so would all
the valid parameters.

Two to five year life span sounds a little short to me. I’ve been earning my
primary income in electronics for over 60 years and my experience shows that
most electrolytic capacitors last between ten and twenty years. But, usually
they will show leakage around seals before they fail. I guess
I retired in 2016 after 34 years as the metrology supervisor at a commercial
nuclear power plant. I couldn’t count the number of equipment failures due to
electrolytic capacitors, WAY TOO MANY. Some brands of equipment had high
percentage failures while other brands had low. Seems the
I don't know that I would run a K3 off a 20A power supply. You're
stressing both. Did you mean to say 30A?

When I built my operating desk, I made the top a full 36 inches deep so
the face of the equipment is about 24 inches from the front. I also put
the 2 pedestals on appliance dolly wheels so I can roll the desk out for
access behind the equipment. There are shelves in the back to hold

Yes. I wish I had thought of doing something
To all interested:
Plain old white tooth-polishing paste, mixed with a small amount of
dihydrous monoxide, and patiently rubbed into scratches with a decent
moistened chamois, has worked for me on bezels of many kinds, even some auto
windows and paint*. Auto polish and clear auto windshield
Check out the various kits for polishing automobile headlamp lenses. They are
all made for this type of work. The more expensive kits have more grades of
grit. I would start with tooth paste though as I have used it in the last on
watch faces with good results, glass and plastic.
