Just aquired a trk-12

I saw a piece at the ETF about replacing them with radar tubes.
IF that does not work, looking at the picture of the real thing,
fixing the anode should be very easy for any glassblower.
Just remove the dag coating in the vicinity of it, remove the old one
by glassblowing, and replace it with a standard pyrex stem HV feedthrough.
Then apply new dag to connect it up.

The problem is of course getting rid of corona at the HV
connection at the outside, but I never had difficulty even
at 15 kV with such feedthroughs.

The neck of course would need a graded glass coupling to
a new gun, and baking would have to be
done at a bit lower temp for longer.


DOES the ETF have any more radar tubes?
