Perhaps I have an older version or that my G08 is a different version, or maybe this has been discussed before that I'm not aware of, but as I was tearing into my G08 and referring to the faq I found it was incorrect in the components pertaining to the Current Limiter Boards (Paddle boards).
It refers to a pair of 2N3904's per board whereas they should be a 2N3904 and a 2N3906 per board.
 
I'm still looking for that "perfect" G08 kit.

I'm told that there were two monitor version to consider necessitating the need for slightly different components. Knowing little about this monitor can anyone elaborate.

Should I pick up the kit from Bob Roberts?(substituting the 6259's or MJ15024GOS-ND for the 2n3716 if I need to replace the 2n6259)

Or if "kit maps" are included:

Biltonix: http://biltronix.com/Star_Trek_08.html#GO8_parts
(Since I also want to rebuild the power supply: http://www.biltronix.com/Star_Trek_06.html)

Below is a picture of the dusty G08 inside my Star Trek.

Thanks.

Please don't use the 2n3716's. I think I ended up using MJ15024GOS-ND. But my monitors still got troubles which I'm thinking are all in the paddleboards.
 
Yes I know. I'll use the 6259's or the MJ15024GOS-ND.

I'm just in search of the best existing kit or component list so I don't have to order from a variety of different places.

Absolutely the best source for help in my rebuild of the G08 was Bill Bouchers'
site. You'll find most everything listed there has all the links straight to Digikey. I've done 3 of his component lists so far.
The G08
The G80
The Cinematronics monitor complete rebuild. The scariest was the G80 where you had to drill the holes in the Power pcb. That was just plain nasty.

Ok, I see that would be Biltronix.

Unfortunately, since this involves ordering each separate component these are not actual pre-assembled kits, so there would be no maps like that included with the kits you get from Bob Roberts.

(That G80 would be a nightmare).

No but you essentially just print out his component list when you recieve the parts. It is clearly edited to show where each component goes. Essentially your shotgunning/replacing components.
Just start from the top of the list, cross it off and hit the next component when you finish. It's not that bad.
 
I have updated the FAQ per your comment, Zinfer, as well as made some other updates.

The newest version can always be found at my website in my signature.

I don't think you understand. The component list doesn't show where each component goes.

This is why Bob Roberts includes a map with his kits.

Yea your right. I clearly don't understand. I've run down through his component replacement list, ordered all the parts, installed the parts on 2 Cine monitors, a G08 and g80 power board.
But I clearly don't understand how I could do any of that without a component map and no board right in front of me that is clearly labeled beside each component.

I might have another FAQ update. I have issue 5 deflection board and the p700 and p600 are screened differently than what is shown here.

FAQ says
Deflection Transistor Harness Connector
Pin Description
1 emitter #1
2 base #1
3 NC
4 collector #1
5 emitter #2
6 base #2
7 collector #2

I am losing my mind now because one of the transistors on each pair is not wired up correctly if this silk screen is correct. My E & C are swapped on the connector and it is the E to left of open pin and C furthest to right. Which jives with the FAQ page but not the screen on my board. These transistors have been replaced as they are MJ21196G and the pins are trifurcon. wondering if it was repinned incorrectly by someone? (note: my monitors is currently suffering partial collapse (missing left side of screen) at this point but was working previously). It would kind of makes sense that one transistor from x and one from y were wired wrong. Just need to verify the screen print is correct.

After more reading and more thought...I think this is wired up wrong but someone please help confirm. Pins 1 and 7 of p700 and p600 are where the +63v and -63v comes in. With the original setup using one NPN and one PNP transistor, you would want Emitter on pin 1 and Collector/Case on pin 4 for PNP transistor. I am thinking someone swapped some parts on my g08 that took transistor harness from an older (non dual NPN setup)? how is my logic? and how the hell was it actually working like this?

I wish I knew more about how the -63 +63 worked together but am backtracking on the above. The FAQ is correct for dual NPN setup and the board is silk screened incorrectly. I posted pics of the two schematics and reasoning for my conclusion here.
