Would anyone have the schematic for the 120mhz Sony rgb amps from a Barco 1208. The black box type part number R7621191?

Not that I have the schematic but what specifically are you interested in finding out ?
If it was a 1208s I might be able to help...

That's about as clear as mud....

I am not good at moving mud but let me try. I want to fit these to another barco projector not based on the 1208.

I'd probably repost your question or change the subject if you can and ask for the Sony pinout. I know folks have mixed and matched Sony and MEC tubes and have modified Barco 1200s that originally came with Sony tubes to use MEC tubes. Not sure which direction you ore going but with the Sony pinout and the MEC one (which I know has been posted before) you should be able to figure out the mods necessary. I have never seen a schematic for the Sony version of those boards. I think Ile who posts here regularly did mod a Barco 1200 to take MEC tubes. The one think to figure out is whether the 1208 with Sony tubes used the same neckboard as the 1200. I know later Barco's with MEC tubes the 9" tubes were rotated 180 degrees versus the 8" tubes (pinout was the same but the tube sockets were rotated 180 degrees to accommodate the variation in tube orientation).

I see what your saying here but I still want use Sony tubes. Its the data and power connections to these neck boards that I want to check out as there are several additional pins that are not on the other 120mhz neck boards. To answer Toms question as well. I intend putting a BG 808s frame in my 1101 and using sony 9" MX tubes as I understand this neck board my well be superior to the two piece 120mhz board and provided it can be done I would like to find out. I also had an idea thats a little more out there, I was thinking before I pull the current ES config apart I might try 120mhz neck boards on the ES tubes which do have to be rotated 180 degrees for these cards to fit, I am not trying for higher resolution here but I would be interested to know if the addition bandwidth improves PQ. The 1101 is based on the 801 which has a lot in common with the 808. In fact most of the parts in this set are from a BG808s.
So if anyone has a schematic or knows what all the pinouts are on the neckboard then that would be greatly appreciated.

Thanks Tom. I have seen socket pin outs before I am looking for the pin outs for the neckboard itself. Perhaps my terminology is the problem here so let me say this there are two connectors on the neckboard (part R7621191) one has 15 pins the other 6, on the normal two piece L shaped 120mhz board there are two connectors one has 9 pins the other 6. So iam looking for the 15pin and 6 pin connectors on R7621191.

I have said to you before that it's not going to happen.  It's not just simple rewiring connector kind of problem, there is needed much more signals with black boxes. If I remember correct some of those signals doesn't even exist in whole 80* based projector.

Thanks Ile. Yes I do recall you saying these required different voltages, (which seemed to me to be somthing that could be altered), but not about missing signals, as you point out a completely different matter.
