Does anyone have a schematic for this neck board?
Thanks

You going to swap yours out for the 909 boards Keith? Id say you may have to go to P19 tubes if you do.

Yes thats the idea. Are the 909 neck boards two piece like the 808s? if they are I would swap the socket part for the Sony socket and if not yes you would be right.

They dont have a socket as such, the tube pins go right into the board.

Sure but is that board removable. On the back are their screws to remove and then the board that the tube plugs into can be removed from the amplifier section which has the heatsink attached?

Just ahving a quick look at the schematics it seems that the signals are the same including the power supply. The pins are different but thats not a problem.

Sure that board is better than the old "120MHz" boards, but I feel these cards are still much inferior compared to a Marquee or NEC neckboard, especially if you look at their price... It would really need a symmetrical neckboard...

Sure but at least it appears possible for me to use the 909 neck board.

Will it be worth the effort?

Not much effort needed, mostly just money 
It would be interesting to know actualy how are those 120MHz boards are doing. What I read is they are barely better bandwidth wise than the even older 75MHz boards, they are just not streak as much.
That barco hybrid IC may not have the best performance amongst the top machines alone, but driving two of them symmetrically for one tube probably would beat everything, so I would start with 6 909 neckboards if money is not object. -Now that would need some effort 
EDIT: Actually this dual IC tweak might give nice results even with the VPJ08s too...

Just turn on peaking that is cheaper

Hello~
Is there a real dual IC tweak?
Is it something like push-pull as 1209/2 black box neckboard?
I'm very interested in

I'm not a Barco guy, I don't know what that "black box" neckboard is, but I can imagine how could you transform your standard neckboard to a push-pull type, but it would require some conversion in the power supply, and the recalibration of the neckboards of course.
I am cheapskate, so I just said what would I do instead of spending high dollar on a not so good neckboard.

I had thought of using those neck boards but you have to also use an older RGB driver board and even older switcher board both of which are known to introduce video noise.

Honestly it's easier to get rid of video noise than getting extra bandwidth at home, or we have to find out how can we mate that black box with newer switcher and RGB boards.

For me that would be a step backwards. I don't see me doing that. If there was a way of mating the black box RGB amps that would be interesting. Case may be right there may not be much of an advantage anyway.

If someone have the schematics for that black box neck board, I would be happy to look at. I have SM for: D808, G1209s, 909, maybe we can work out something...

Shouldn't be too hard to find as those neck boards were used in 1208 1200 1209 series projectors.

Unfortunately I didn't find much info about them so far, only that they use dual VPA13 chips, which is a good start as the more recent XGs are using these too and they have quite impressive bw (except mine of course  ), and there is the oportunity to push them even further with the VPA15H found on sony 1292 neckboards... (sorry Keith  ) Some would chimne in and say drop in some VPA18 instead because it is very kickass, but the thing is the VPA18 is a low voltage chip, while the VPA15H is a high voltage chip, so the slew rate of the VPA15H is even better than the VPA18's so that's the way to go.
But I still don't know what signals do they require.
