I can only go by what I see there Gary.

I don't understand, you first solder the connects then you come back and clean them up later. Hmmm, can you say cold joints, but of course you probably don't know what that is or what causes them. You make it sound like I'm a beginner at soldering, I was doing this sh!t long before you were born sonny boy so don't get too cocky.

As for the cables, I was referring to the inter board cables. As for the connector I referred to it is the one on the RGB driver board from the switcher board. Well for long runs yes of course a belfoil coax is better but you're only going inches and that small crappy cable was meant for short runs inside equipment.

I don't recall saying anything about trashing any connectors.

Well at least I can say I know something about electronics unlike you who doesn't seem to know the difference between a 50R and 75R cable or why there is a need for both in the case of the Barco.

As far as wishing you luck I sincerely meant it, I hope your rebuild project turns out and it looks better than new. But of course you're too imature to take it that way or any flak for that matter.

Before you start knocking things perhaps you should educate yourself first. But I guess because you've done this before then you are the expert in this area.

Relax Gary, take a pill and get back to modding your 9"er. I love chatting with you because you get upset so easily and tend to lose it, nice. Don't take it to heart Gary, I'm just bugging you.

Gary take a closer look at the connector with the white wire on the right side of this picture, it looks like its burnt a bit, not sure if you noticed this or not. I wonder if this could be related to your problem.

I don't know Gary, what "is" your trade?

I have a sore spot you? Well I guess you shouldn't trash people like you or did to me by adding words and saying things I never did say, but I guess that's just the way you are.

You're absolutely correct Gary, it doesn't take an EE to build a simple cable or a balanced transformer, but it might to fully understand what it does and how and why. I never claimed to be the expert in the video field as that's not my background in electronics. As for soldering, practice makes perfect.

Again, I never said anything about you trashing any connectors, learn how to read.

Just in case you didn't know, but I'm sure you do, the coax running from the switcher to the RGB driver board is 50R imp., the coax running from the RGB driver board to the neck boards are 75R imp.. Now does it make any difference if you use 75R in place of the 50R, for that short of run no.

I think somewhere on Beldens site there is a white paper on teflon core coax cables and their advantages in HF. Even the best sounding audio cables use teflon insulation.

As far as you using what connectors, in the pic of the 2 vid boards it appears like you are still using the long PCB style connector, or are the wires soldered directly to the board and if so then why do you still have the connector there?

Gary I don't mind and I wouldn't mind helping you out with modding your Barco video path and other things to help out the Barcos but damn you gotta lighten up and be nice for gawds sake. I've exchanged info with Anthan to help him with his Marquee and I don't think he found it too hard to talk with me.

But that's okay Gary have fun and don't let the smoke out for crying out loud.

Athanasios,

I thought I had read in one of Garys posts that he was going to get Greg to mod his boards. If I'm not mistaken I believe Greg is asking about $1200 for modding a set of boards, not sure what boards he actually mods but that is a hefty price for modding boards.

AH yes, the pooge articles, I am very familiar with those and with audioexpress, I have/had most of the mags since about late 70s I believe it was. Lots of good reading, and I do remember the talk about soft recovery diodes which is what I used in the power amps I designed, well I guess I should say I used them pretty much in every audio piece I built. Actually I had to replace one in one of my poweramps just 2 days ago, it shorted, don't know why or how but I had spares. Another thing I did was put ferrite beads on each of the leads.

Yes one on each lead.

I don't recall the Marquee schematics off hand and I'm not sure where those transistors are in the circuit.

Walt , lets discuss this on the Marquee thread when I get to it. Gary , you can have your thread back !!! Wink

Well Gregs certainly talks a big talk, but having talked with him via email many times over the past year I'm not so sure just how extensive he knows the Barcos like the back of his hand, leaves a big question mark in my mind.

Now that's not to say his mods don't make an improvement over the stock boards, just how many percent points are we talking, Greg seems to think his mods make a 100% or was it 200% improvement? Hmmmm whatever Greg, it seems over the past there's been a few people question that including me. I know what gains can be made to the Barco video chain with some mods, does Gregs get there I don't know never seen them, a few people say yes, but then again maybe they haven't seen other peoples mods to compare them to.

Gary, you seem to be on the ball, why don't you do the mods yourself and save alot of money and learn something along the way.

IMO, Greg is a bigger BS'er than any other engineer I've ever known, and incoherent in his written communications 50% of the time (another strange trait for an engineer). But certainly a nice enough fellow, with some good enhancements to offer. He's also really short on followthrough, having promised to share information many times, then failed to do so.

Gary, I'd agree with Walter that doing it yourself would afford you an opportunity to learn a lot, vs. just sending your boards off to be modded, waiting, then dropping them back in. You seem to have time available, though it would be a hit to the immediate gratification aspect. Wink

Also, I'm a bit concerned that if you don't take the time to get your PJ running first and evaluate it, you won't be in any position to say what kind of gains you see from getting the Eisemann mods. So you really wouldn't know how "worthwhile" they were to you. If you do go that route, set up the PJ first, take some time to get to know its strengths and weaknesses (watch a few films!), THEN get the mods. At that point, I'd be interested in hearing your comments.

I would be interested in doing a DIY mod that improved performance, but Gregs boards are out of my budget. I can solder fairly well, (done some SMT work succesfully) and have been dabbling since I was 9yrs old. I know a little about electronics but no longer own a scope. I'm very interested in seeing Gary's finished mods.
