Electronic Component Replacement Lists:

For many folks, the most difficult part of any restoration project is repairing the circuit boards. Aside from troubleshooting the circuitry, the next greatest challenge is purchasing the required components. The hardest part of doing that is simply figuring out the part numbers. The art of determining exactly what to buy and where to buy it is called sourcing. Over the years, I have been relatively proficient at this task. I am providing the following lists in the interest of helping others to repair and maintain their machines. I endevour to prevent errors, but you are ultimately responsible for your own projects. I will not be held responsible for costs or problems related to errors in any list on my website. If you encounter an error, I would appreciate it if you email me a notification of the error so that I can correct it. My lists are going to be limited to those games in my collection that I've repaired and/or restored.

Galaga

Repairing this board involved getting some custom chips from Mike's Arcade and some old memory chips from Arcadechips.

I also had to replace the 50 conductor ribbon cable and the PCB headers and I got those from Digikey as follows (Aug.31, 2006, Stock Prices last updated Sept. 16, 2007):

Space Duel, Black Widow, Gravitar

My work with these games mostly involved rebuilding the WG 6100 color vector monitors. While I could have sourced 99% of the parts from Digikey, I decided to go with the deluxe 6100 kits from Bob Roberts. I also installed the very popular LV2000 board in one of them, purchased from Arcadeshop.

Update June 15, 2009:

WG6100 Color Vector Monitor Rebuild Kit:

Due to popular demand, here is a table of WG6100 parts available from Digikey. I have used the Digikey components listed below in my 6100 rebuilds with great success.

The list includes the most common primary parts used to rebuild the 6100 monitor. Be aware that this is not a complete bill of materials. These are only the most common components that need to be replaced and these are the parts provided by the majority of kit suppliers.

Also shown are the parts listed by other kit suppliers as so-called "additional parts" that can optionally be used if you want to be very thorough. They are marked by a '+'. Some suppliers provide a disclaimer citing that these parts cannot guarantee extended or even ideal performance due to a lack of official authorization from the monitor manufacturer. I always install them and my monitors always work great. My first units rebuilt in mid-2005 are still running strong and have never had a problem.

WG 6100 Monitor Extension Cable Kit:

If you are capable of crimping Molex terminals onto your own wire, then you can easily make a very handy extension cable for your 6100 color vector monitor. A few people sell the complete cable assembly for about $40 but the total cost of parts (including good quality 18ga wire) for a two foot long cable is only about $11. When assembling your cable, note that you may omit position 9 terminals and wire. All other positions are wired 1 to 1. Don't forget that when you hold up both ends and look at them head on, they mirror each other. Make sure that each wire mates with itself if you plug the two ends together.

The tools and wire that I listed are quite expensive but I'm sure you could find cheaper generic wire and a crimp tools at your local hardware store. Personally, I bought the universal crimp tool and extraction tool listed below because they work on all similarly sized Molex connectors. With respect to the arcade hobby, I use them a lot so it was a good investment regardless. If you only need to make one 6100 harness, just by the required parts listed in the first table, borrow your buddy's crimper and invest an hour of your time and you'll save $25 over buying one complete. Just don't cross any wires!!!

Transistor Substitutes Introduction:

I have recently been sourcing components for wg6100 and Sega GO8 (and other vector) monitor rebuilds and I've collected some useful intel. I know that it can be a royal pita to source the big 2N3716 (NPN) and 2N3792 (PNP) and 2N6259 (NPN) transistors. They are not impossible to find (i.e. Bob Roberts, Newark, etc.) but sometimes they can be hard to find in stock and for reasonable prices. Worst case, they come from the USA by mule or the UK by sea-monkey and you have to wait for a few weeks or longer to get them.

I have seen posts in the past asking if there were any subs available... well, there are plenty, so here you go.

All of the substitutes that I have listed below should work, but I have not tried them all personally. Other people have tried and proven many of them, if not all. Many of them are actually superior to the original device. I just went through all of their datasheets, all of which I found on the Digikey site. The parts with the parameter (ft = 2 MHz) are known to work okay. The original 2N3716/92 parts have ft = 4 MHz and so do most of the subs listed below.

Any part having similar parameters such as...

• Ic (max collector current) equal to or greater than the original part spec
• Vce (max voltage) equal to or greater than the original part spec
• second breakdown (Is/b) equal to or greater than the original part spec
• similar gain (hfe about 60)
• same TO-3 case
• same bandwidth (ft)

...will work as good replacement parts. All of the parts listed below meet these requirements.

If anyone tries any of the parts listed below and it fails and is known to be the root cause of failure, please email me and let me know. I will add such reports to the list or remove the part from the list.

Before I make this next statement, I want to say first that I have the greatest respect for Bob Roberts. He is an honest and very experienced and knowledgeable person. He has contributed immeasureably to the arcade hobby and business for many years and the world is a much better place because he is a part of it. That said, I also want to say that although Bob's monitor rebuild kits are wonderful, you must be aware that Bob's GO8 kit comes with 2N3916 transistors. These are sorely inadequate for the GO8 and they WILL fail almost immediately after installation and most likely lead to the immediate destruction of several other components as well. Many people have learned this lesson the hard way. Bob has been notified of this but as far as I know, he has not changed his kit contents.

DO NOT INSTALL 2N3916's in your GO8 monitor !!! You have been warned.

2N3716 (NPN) and 2N3792 (PNP) Substitutes for monitors:

• WG6100 color XY (i.e. Space Duel, Black Widow, Gravitar, Tempest, some Star Wars)
• Atari GO5-802 mono XY (i.e. Asteroids, Asteroids Deluxe, Battlezone)
• Cinematronics / Vectorbeam mono XY (i.e. Star Castle, Space War/s, Armor Attack, Rip Off, Solar Quest, Tail Gunner, etc.)
