All sony tubes have same pin out, that is totally different what Marquee tubes have. That is usually not big problem, but Sony tubes need extra focus voltage (about 15 kV) applied to pin 1. I believe that there is no easy way to get focus voltage to neck boards in Marquee.
Other way around this would be much easier.

Ile,
So pin 1 (labeled "Arc Suppressor") in the .pdf diagram above takes an additional focus voltage? What would happen if you didn't supply that voltage?
Thanks,
Ben

I thought only the ES tubes had a focus voltage applied to them.

Thanks,
Ben | Yes that same pin. Newer tested without it, but I assume that tube won't work correctly.

Sony EM tubed Barcos, like 1200 and BG808s have this extra "focus voltage" applied to pin 1.
1292 probably have similar voltage connected.
Not sure if focus voltage is correct term, but least Barco use that term in SM when voltage leaves Quad. Then G2 board have focus/G2 block that divides dropped voltage to each neck board and to G2 board that use it for G2 voltages...

I have used sony tubes in a BG1200 without the additional (5kv?) wire connected for some time. Tube worked just fine.
I forgot to connect the wire while working on the projector.

The "arc suppressor" pin can be connected to ground. The Sony 09MI tubes in my 4200 have that pin grounded and its worked fine for many thousands of hours.

Rewiring neck boards takes about fife hours, if you have glue what you are doing.
You probably know that it's needed to remove LC hardware from both tubes and glue mfx3 to Marquee hardware. Other option is that you use 1292 tubes as is and build your own attachment system to Marquee. Both ways it's lot of work, I'd say least ten hours both ways.
There is also chance that mfx3 wont fit to Marquee LC hardware, because Sony tubes could have little different shaped face plate. MFX3 is also very long tube (15 mm longer than MI/MX), so there there is chance that it won't fit to Marquee tube housings. Also neck connector is 180 degree twisted, so does Marquee tube housings have room for twisted neck board, etc...
Marquee tubes will be available longer and tube type is more robust. Sony tubes have glued face plate that is weakness, also rebuild can't be done.
I have bare mfx3 here, so I can measure it if you still want to do this.

That would be me. (The mix was temporary, I'm running all sony-pinouts now)
My case is a bit different, though, because the tubes I had weren't Sony tubes, but rather oddball, P19LUG copies with a Sony pinout. So the tube internals were equivalent to P19LUGs, which is compatible with the Marquee. What I did have to do was extensive reworking of the neckboards to accommodate the Sony pinout. If you want, I can take pictures of what I did and post them up.

I have only 8" Marquee tube housing and ac hardware here, so I can't tell if it fit to 9".

Hey voodoo,
It might be a little bit before I have my PJ apart to take pics, but when I do, I'll post them up.
