That's unfortunately not the case, Dan. Everything Wichita turned out up
until the mid 60s used Ohmite wirewounds. Of course, they would burn out
right where the wire got the hottest ... where the resistance of the bulbs
and the resistance of the pot were the same. THis was almost always 10%
or so from the high side contact of the pot.

. Wirewound pots
aren't common in the resistances used here and they cost too much.

I bought correct ones from aircraft salvage yards for $50 -$70 each. I
sure would have like to know the part number for a replacement.

If anybody has an old one laying around, burned out or not, and you can tell
me the airframe it came out of and send it to me, I'll cross it to the
correct Ohmite part with a Mouser part number.

Never ever forget that every part on the airplane was supplied by the lowest
bidder.

My Cessna use a wire wound pot that kept burning out. I took one apart and
was it cheaply made.
