Just curious, anybody left that will fix G08 monitors? Arcadecup looks like they stopped for whatever reason, "P&L Video games" in CA will not pull up a working website for me. Does "Mongo" fix these for klovers?
Zonn Moore has informed me that WG6100's are "too slow" to run SW, ESB or MH without flicker on the ZVG card, unless someone here has one running these games without flicker somehow, I would like to know more.
My P4 2.4 pounds away at vector games but then when I go into zvg output, I get frameskip on these games. Zonn seems to believe that the "bottleneck" is the WG6100 monitor.
 
Interesting, Im not so sure how true this is but I have been told the G08 produces a nicer vector picture than the WG6100.

If the WG6100 is too slow for SW, ESB and MH, how come it copes ok when using the PCB?

Im building a ZVG setup, but using a Amp.

Because MAME is drawing the vectors all at once on the screen as it were a vga display, unlike an original PCB. The vectors are not drawn the same way as original but this is getting into "rocket science" for me.
I would be very interested to see how your Amp handles these games and what computer you will be using. I actually tried a faster, hyperthreading computer and I still had frameskip, so I'm not certain that the frameskip is due to the computer cpu, so I asked Zonn and my interpetation of what he tried to tell me above was his answer.
He actually said the G08 was the fastest of all the vector monitors BITD, so if one had a working one, it may be an ideal candidate for a zvg setup.
So the only reason to stay with dos at this point is to utilize all the previous work put into the game lists and menus, not saving processor power, if what Zonn is saying is correct.
Recent versions of guimame will offer so many video processing options, more than command line mame.
 
I was offered a G08 but was frightened off with talk of parts being difficult to source for it, and the fact it is difficult to repair.

I am using an AsRock 4CoreDual-SATA2 motherboard with E7600 CPU, not got it all together yet.
 
Although I will work on monitors for others I don't typically do "mail in" work. I have two years of projects lined up (games, cars, landscaping, remodeling, ect) and the ONLY way you can get pushed to the front of the line is if you show up at my house in person. I cannot make time for more work... I have enough of that already. I can always make time for friends with beer while we fart around with their project in my garage.
 
I have worked on a few in the last couple of years and maintain a couple of my own.

Contrary to popular belief, once fixed, they generally stay fixed.

I currently have one from another klov'er and will return it after I finish looking over a bad sound board of his.

I would be open to another repair after that, but only one at a time. I don't like to be swamped with things to do and am generally in no hurry to get things done. If something seems too much like work, I tend to avoid it.

In terms of all the G08 mods and advice out there:
-I like the main transformer lug switching. Simple and effective.
-I do not like mounting the transformers upside down on the heat sink. Plain ugly and possibly ineffective.
-Healthy ground connections throughout- I have introduced a healthy AC hum in the picture with this one. I guess it should be done correctly.
-NTE388 replacements for the 2N6259 transistors- I have seen many 'new' 388s shorted out immediately on power up. I don't know if they're from a bad batch or simply a poor match to some specific electric requirement. William Boucher (biltronix.com) has some alternate replacement advice that I have found very sound.
-Mark Jenison's G08 faq- very nice- I always have a copy for reference along with several photocopies of zoomed in schematics when I work on these.

Let me know if you need any help.

I don't think P&L has ever had a website. The last phone number I have is 626-337-9782.

I haven't been over there in about 6 months but I assume they are still around.

I actually talked to them about G08s last year and although they haven't had one come in in a long time, they have indicated that they will work on them.

The knock on these guys is that they only fix what they find wrong, and don't go through the whole monitor. They do have a warranty on repairs...
 
Thanks for the replies guys. There's an interesting dichotomy for the information I keep getting about this particular monitor; on one hand, it has a reputation of high failure rate and to possibly actually set on fire, on the other hand, I keep hearing that it is the fastest and brightest vector monitor of its' time and it is the ideal zvg monitor for these reasons. If I'm lucky, I may get my hands on one of these soon. Interesting thing, is that if I can't get a set of Sega boards to work in a "fixed" G08, the only way I could test IS with a zvg card.
 
I've never had a problem with mine in the three years since it was repaired by Chad.

However, it's used only sparringly when I have the game on a few times a month for maybe an hour at a time. I guess if it was in commerical use 12-15 hours a day, as it was designed to be used, there might be some issues after a while. Hard to say. About 1 or 2 times a year I turn all my games on for about 12-15 hours just to see if they can make it all day. Most do.
 
I brought one back from the dead a year or so ago, and as far as I know (sold the game) it's still functioning. I did the transformer mod to decrease the input voltage, and I think that makes a big difference.
What I noticed while working on it, is it appears it was built by a factory full of drunken monkeys. The quality of the soldering and general workmanship of the monitor was horrible. I had to resolder damn near everything to get the monitor to function.
After getting it working, I decided I never want to work on another G08, and I have no desire to own a Sega vector game.
