Neotec nt35 screen resolution
« on: August 10, 2017, 10:50:07 pm »
Sup gang?! I have maximum force showcase with a 39" tube in it that is working with standard resolution pcbs. The monitor chassis is marked NT35C.  Is it possible to use this tube but somehow get a 25kHz signal through the chassis?

no.

the yoke's resonant frequency is tuned to 15khz. trying to run it at a higher frequency results in a pile of heat being produced until failure. manufacturers dabbled in switching between 15k and 25k but the yoke just end ed up getting cooked or were never really good at either frequency.

more modern switchable monitors used a yoke often active electronics on the yoke to vary the resonant frequency to make it run somewhat efficiently.

if you need to switch to 25k, you are likely looking at finding a 39" 25k monitor and swapping all the guts and yoke over to your tube.

a universal chassis MAY work, but they are pretty impossible to find, and even harder to find the CORRECT one for your monitor. you still end up running a 15k yoke at 25k though.
