I've acquired a couple of 9" monochrome CRTs with the intention of transplanting. I've seen it done, but wanted to go through the steps all myself.
I'm starting with a used green-phosphor Matsushita CRT that came out of a CNC machine.
A little burn-in, but I've got it, so might as well pop it in.
We'll start with hurdle #1 the fitment.
As you can see, the original CRT on the left sits lower, so some stand-off construction is in order.
The overlap is quite awkward...
The first run of the stand-offs. The dimensions were almost 100%. I decided not to print the full height for this test
They fit like a glove though
I decided that since the clearance is so tight, the screws that mount this CRT to the stand-off pieces will go in at an angle, pointing inward.
So I'll need two separate models, basically a mirrored version of the one. Hopefully I'll have enough sleep tonight I'll be able to fill the gaps. I'll keep updating as I go along.
Edit: I'll also need to lop off a bit of the circle section to make room for the analog board.
