My father had
some ham radio related device with a one inch CRT in
it. That basically looked like a 6L6 with a white top ? including
having an octal socket (8 pins). That?s even harder than the device you
described.
MY guess is that onyl one of each of the X and Y plates was brought out
to a pin, the other 2 were internally connected to one of the anodes. It
works, but the linearity suffers a bit. OK for monitoring on a 1" CRT,
not for meaking measurements on a 6" CRT?
You?re right.

pins; one of the 8 is marked no-connect.
