[Milsurplus] APN-9 Question

[J. Forster]

Hi Antonio,

I would be very surprised if you have an APN-9A.

If you look at it from the front, as an operator would, it appears the
added assembly to the right of the CRT and about 3/4 of the height is
removable. This assembly appears to be removable.

The question is how?

Thank you,

-John
