May I put the Sony 07MS tubes in an NEC 9PG extra????

Have three new tubes, and may get an 9PG extra with burned tubes.

Or what PJ look for the SONY tubes????

Thanks Daniel

These CRT's will not fit the NEC projectors. If they are 07MSP's, they'll fit Sony 1252 and 1272 projectors. I believe the 07MS fits the 1251/71 series.

Don´t do that Daniel.


The NEC-CRT will be worse with that tubes.

Why do you ask this ? Do you want to buy one with these tubes? If yes, look for another seller who have a good reputation. Ask Oliver K. for example. He lives in a town near you.

07MS tubes also fit Electrohome ECP projectors, 25xx, 35xx and 45xx series projectors with no modification and will fit in other ECP's with minor mod's.

I've seen the Sony 7" tubes side by side with the NEC 7"tubes, and the NEC's are MUCH bigger. You'd never get the Sony tubes to fit in an NEC chassis in any way whatsoever. Put Sony tubes in a Sony or Electrohome(and some Barco's?). The tubes from the NEC can be rebuilt by VDC.

The 07 MS tubes are used on the Sony 103x, 104x pjs, while the 12xx pjs are equipped with the 07MP(S) tubes, much bigger (sometime considered to be 8 inches, sometime no. mounted on the Barco 8xx series too).


The 07 MS tubes are the most widely used 7 inches tubes in the whole world. Sony, Barco (in the past, not in the Cine series, but in the 701, 708, 508, 600 and so on...), Electrohome (in the 31xx, 41xx, 35xx and 45xx), RCF (all the 7 inches pjs), SIM2(all the 7 inches pjs)... for example use that kind of tubes.


You cannot mount that kind of tubes on the NEC pjs. The NEC tubes are totally different. Taking apart that normally the NEC tubes are considered to be better (in image quality, specially in colors) then the Sony 07-MS, the major difficult would be:


1) the different size (the NEC tubes mounted on the 6/9PG series are much bigger, considered as 8 inches);

2) different shape and mechanical mounting;

3) different electrical parameters (like focus and G2 voltages, the anodic voltage is the same, 34 Kv...,AFAIK);

4) different color behaviour (you should change all the three tubes togheter, starting for the fact that you will need a lot of mods, on your pj...).


it's just a consideration/suggestion. Avoid to do that.
