Bought some kallax units yesterday to properly store and display most of my CRT's (one 37cm TV is still in storage as i didnt have space to put it here with the rest and one is undergoing repair) so things might still change a bit but for now i'm happy with the results.
While my other small color CRT is undergoing some repairs i couldn't help myself and bought another 16cm / 6 inch color TV. Its a NEC CT-6A1P-2B2
It was extremely dusty inside and out and the potmeters for controlling color and brightness where very scratchy so i cleaned the whole thing, put some contact cleaner on all the pots and now its working great. A nice addition to my CRT collection, its a shame its RF only and the screen has a bit of a greenish tint to it, didnt look too much into it yet if that's adjustable.
Edit: greenish tint was easily resolved by adjusting the gains
