So the frame from the WG D9200 will not work?
Correct, the entire tube must be stripped and backmounted to the Nanao frame (what I've been saying this entire time).
If you are saying that I need the Nano old monitor frame and put the WG D9200 in that frame them I have a problem
Yes you have a major problem!
The ONLY frame that will ever fit cleanly into that Blast cab is a Nanao.
You don't need the Nanao tube, chassis, neckboard, blah blah... But you can't mount without that frame period.
I've been scratching my head this entire time, as to why you sold a Vewlix L cab with a beautiful new LCD in it.
Just So you could buy a busted Blast City and put a crap WG (haha ok they aren't crap but they are a far cry from the quality of a Nanao) monitor in it?
Esp the part where you said you have fear about necking a tube... This procedure is neck central because you have to handle the tube bare (without a frame).
Then rebuild the entire monitor using a frame that wasn't designed to fit it properly (hence the necessary back mounting of the tube).
Just wait until you get to mounting the chassis, none of the Nanao frame holes align to shit... I did it with a piece of scrap plywood acting as an adapter plate.
