Which games does this monitor go with? I am pretty sure Star Trek.
Can anyone give me some background?
Thanks.

The monitor is specific to Sega Color Vector games. It is NOT plug and play compatible with any game using an Amplifone or a WG 6100.

The first version G08-001 uses chassis transistors that are nearly impossible to source. They were also prone to bursting into flames.

The second version G08-003 (there is no 002) had some fixes incorporated that solved the fire hazard problem but people never trusted the monitors again. The 003 version uses fairly rare chassis transistors.

The rebuild kits from Bob include common transistors for the monitor that should NEVER be used. The chassis transistors on the monitor should be re-used if they are not bad.

Those monitors are worth a bit of money (about $300-350) if fully working. The picture tube is the same as used in a WG 6100 (the yoke is not) so even a hopeless chassis with a decent tube is worth a fair amount.

The HV transformer has not been reproduced and likely never will.

Hope this is the kind of info you were looking for.

Apparently 'thermal events' are still possible on the -003 models because the previous owner of my Star Trek mentioned that it happened to the one that he later sold me.

In this case it was a resistor that went up and he replaced them with 'flame proof' resistors -- or so he said.
 
The current protection board will burn resistors and transistors when the output devices fail. There are custom ICs on the deflection board and HV board that are NLA also. Its a PITA to work on due to the spaghetti of wires. That and the expensive parts that blow easily make this a labor of love.

Thanks. All info helps.
I need one of those games to test it.

Not plug and play...
But an adaptor can be made?
What is monitor pinout please?
I can try in Space Duel with adaptor?
 
I do not know of an adapter.
Monitor pinout can be found in any of the Sega Vector Game manuals.
You CANNOT put this in a Space Duel. I don't even think you can use one on a ZVG setup if I am not mistaken.

Even if you can come up with the right voltages to run it, Sega and Atari/Wells Gardner approached how to shut off the Z voltage differently. I think Atari had patented the "Spot Killer" circuitry and Sega had to come up with something completely different to avoid legal problems. At least that is how I remember it. You need to do some research beyond this site on your monitor. There is a TON of information about it.

I think ZVG does support it, however:

1. G08 is +- 45 volts input (90v AC Center tapped)
2. 6100/Amplifone +- 25v input (50v Center tapped)
3. Theres a circuit out there that can adapt the signals. The XY voltages are different and I think the Z is different.

Your going to at LEAST need a Sega power supply to run it no matter what you do.
 
How would one determine if the monitor is a G08-001 or G08-003?

Thanks.

I agree with that.

Also, look at the printing on the transistors attached to that giant heatsink on the right.
If they say MJ something or another, it is probably a -001. If they say 2N6259, it's probably a -003.
 
I don't know what output limiter boards" are and cannot find any "giant heat sink", but I guess I can operate under the assumption that I have a G08-003.

Thanks.

Ok, I can barely make out a faded upside down XXX259 on the bottom transistor, so I guess that means I have a 003.

Thanks.

I have only seen -03s with one exception of a -01 with a necked tube. I have had about 9 of these monitors. I think most were converted except for the ones that got stuck on a shelf and never fixed.
