If you had to choose which chassis to rebuild, assuming the condition of the boards looked similar between the two, which one would you prefer? Which one is better between the K7000 and K7203 and why?

I have both of these chassis that I can work with and debating which one to rebuild. I'd rather rebuild the one that may be of better design/quality/picture/etc. but not sure what the difference might be between these two designs.

Thanks!
 
K7000 all day - these are super easy to work on, parts are cheap and with the exception of a weak-ish flyback they are super dependable. These are an absolute arcade standard. I think most people will agree the later Wells chassis are far more problematic.
 
The K7203 chassis is the chassis they switched to that didn't require an isolation transformer. So it can be used in a cabinet with an ISO or in a cabinet without an ISO. The K7203 isn't really any harder to work on then the K7000. It basically is a K7000 with a SMPS (switch mode power supply). Just like a switching power supply in a game. That is why it doesn't require the ISO.

Both are excellent monitors.
 
How about failure rates of flybacks? I read somewhere that K7203 flybacks might be more reliable than the K7000. Any opinions?

I've robbed a 7200 flyback to fix a K7000 once. that was back in the dark ages however. :p they're compatible, but different part numbers. I would imagine the 7200 is probably about the same as the later black knob K7000 variant, which I see fail significantly more than the white knob ones (of which, still, in my 11 years of doing this, I've only seen 1 go bad, ever)

unfortunately the reproduction flybacks aren't any better than the factory original ones, and depending where you get them, may actually even be worse. while we have the stuff just keep changing them when they crack or go bad.

clarification: the 7201 uses the 641 flyback which will interchange with the 528 from the standard k7000 but neither will work for the k7203 which uses a tft014000-1502 (ct-8584).
