Thanks! :')

Yes, I did notice that. Last night upon closer examination, there appear
to be
2 more pins from the necktube than the 19VLUP22 had. Picture a clock with
1
pin at 12:00 and 7 pins around the clock starting at 3:00 and ending at
9:00 for
a total of 8 pins.

The Disco tube has the following arrangement:
1 pin at 12:00 and 9 pins around the clock starting at 2:00 and ending at
10:00 for
a total of 10 pins.

So there are 2 extra pins! They are likely not used but I'm curious what
you did to
transplant the tube to the GO-7 as the GO-7 schematics seems to show only 7
pins
total as well.

It is a really nice tube - best of all, there are likely tons of them
hanging around as operators had Disco chassis board failures constantly.
(My operator contact has several on a shelf).
