Well, the first of the HP 6216A PSes I got off Ebay arrived, and the
only apparent thing wrong with it is the pilot lite id burned out.
It's a 125V lamp inside a 5/16" plastic sleeve that is press-fit into
the faceplate. It came out easily, but I have to do some surgery to
the plastic sleeve to get inside.

I was thinking that I might be able to find a replacement 125V
incandescent lamp that would fit inside the 1/4" inside diameter
plastic sleeve, roughly the same size as the body of a cheap Bic
ballpoint pen. I would imagine that it was very low current, maybe
only a quarter watt total dissipation. From pics I've seen, I'm
fairly certain it wasn't a neon light. If I can't find a lamp, I
think what I want to do is replace it with a regular LED, but instead
of having it connected across the xfmr primary, I'd steal some current
from the secondary's rectified and filtered DC. I know I can't get a
LED, rectifier and resistor inside the sleeve and keep the power
dissipation that low using the 120VAC.

I bought a manual for ten bucks from Ed Matsuda, but it will arrive
next week. I believe it has a schematic. I would like to make sure
the supply I'm tapping into won't mind a bit more current. It might
affect regulation or something. I was wondering what others have done
in the same situation.

Can you post a picture of the pilot light on A.B.S.E?

Once you have the service information, you should be able to see what type
of lamp it is, and order the original one. This way you will have a proper
repair.

I just took a pic, I'll post it in a minute.

That thought had occurred to me. But the PS only cost $25, and a
replacement lamp would eventually burn out again. Besides, I thought
the look of a blue or turquoise LED would be really cool, and last
forever. I won a bid on another 6216A, which will be arriving this
week. It will likely have the same problem, a burned out pilot lite.
I also bid on a 6214B, probably get that next week. Same story.

With that many almost identical looking PSes close to each other, I
figured it would be nice to give them each a distinctive look by using
different colored LEDs for each one.

Radio Shack sells a small neon lamp that would fit in a 1/4" hole.
It is 125vac, has two lead wires, and the case is also the lens.
The barrel is threaded for a small nut and washer. The top of the lens
sticks out about 1/4".

I would not re-invent the wheel here....... just install the Radio Shack
neon panel lamp (125V with built in resistor) and hook er up to the
transformer primary ..... using the same wires that the burnt out 125V
incandescent lamp used. No drilling, no fuss, no mess.

Well, so far no drilling, no fuss, no muss, and it now has a blue LED.
I received the manual for the PS (with schematic and parts list), so I
have something to guide me. One thing I noticed was that the pilot
light was connected to a pin on the transformer, this pin had no other
wires connected to it. I looked in the schematic, and I saw that the
primary consists of two windings, designed to be connected in series
for 230VAC, and in parallel for 115VAC. Well, accodring to the schem,
the pin with the pilot lite is unconnected, so that the whole unit is
being fed AC thru a single winding. The winding with the pilot lite
is acting like a secondary winding and driving just the pilot lite! I
don't know if this was a factory goof - they forgot and left out the
jumper, or if it was supposed to be that way. The PS still
operates...
