The task at hand is driving a 4" diameter vector
CRT. _Any_ 4" vector CRT
would work, but it has to be round.
As you have probably found out by now, 4 inch CRTs are real oddballs. The
only "production" (that is "over the counter") CRTs of this size I
know of
are the 4AP1 and 4AP10, and they are almost nonexistant.
I have to be able to drive this from
a PC. I'm building an F-15C flight simulator out of real parts - one of
which is the mortal remains of an ALR/56C electronic countermeasures
display.
Frankly, your best bet is to find another AN/ALR-56 display. One should
turn up eventually. What is the IP- number of the box?
The original electronics are basically junk due to
excessive
shock from ground impact.
Crash?
