    Some time ago I heard about the design problem in a large number of Williams games. The problem is about missing the fuses in the 18V (controlled lamps) and 34V (solenoids) circuits before the bridge rectifiers. Because of the missing fuses things can go very wrong with these games. When a short occurs in a bridge rectifier there is a possibility of burning wires from the transformer to the bridge rectifiers. In worst case scenario even the transformer goes up in smoke. In the best case the main fuse blows and turns the machine off. To remedy this problem simply placing fuses in the circuit before the bridge rectifiers is advised. A very doable solution. Another problem could be the very large capacitor in the 18V circuit. The life expectancy of 10 to 15 years is already long past for all machines. Now isn’t that much of a problem for the controlled lamps, but the electronics might object. When your controlled lamps burn less bright there might also be a problem with the bridge rectifier. All these problems can be fixed by using my brand new Bridge Board.

    On this new board are the bridge rectifiers, capacitor replacements and the newly added fuses. These components can continue to serve you for another 10 to 15 years and replacements are easily available. Simple screw connections, no soldering skills needed. The bridge rectifiers are on the back side of the board and are also used for mounting the board in the back box. This way the bridge rectifiers have the best cooling thru the metal back plate in the back box of the machine. If you want you can also mount the bridge rectifiers on the front of the board, but an extra cooling body is advised and the use of mounting spacers. Additionally this new board also has 2 leds for checking if the exit power is present.
    Brug Bord 02 klein.jpg
    You can use this board in ALL games from Williams System 3 up to System 11A. Data East used a lot of technology from Williams. So you can also use this new Bridge Board for Data East games as well. Even the first 4 games from Sega too.

    I do have to mention that Williams solved this fuse problem from System 11B. From this series Williams used an Aux. Power board which has the fuses added. Data East solved this missing fuse problem from their 3rd game (Time Machine).

    Despite of the solved problem in Data East games, you can still use the new Bridge Board to replace the large expensive capacitor. The big advantage is that you also replace the old bridge rectifiers and the fuse holders all with one new board.

    The price for this Bridge Board would be 30 euro ($41) plus shipping. Shipping to countries within the EU would be 15 euro ($20). Shipping to the USA would be 25 euro ($35). Combined shipping is advised to keep the shipping costs low. If you have any questions about this board or its connections, please send e-mail me at inkochnito @ kpnplanet . nl or inkochnito @ gmail . com.

    Here are a few images of some games and the situation in which you can use the Bridge Board.
    Please take notice of the components placed in the red circle.

    Sega Maverick, please notice the second large capacitor for the large DMD.
    This one can also be replaced with a Bridge Board.
    So for Sega you would need two boards.

    As we speak I am working out an agreement with Todd from Big Daddy's Enterprises.
    He is willing to be distributor for the USA.
    More to come.....

    #8 4 years ago

    Todd is a great guy, deal with confidence.

    #9 4 years ago

    This looks cool. Can you post a pic installed?

    #10 4 years ago

    Great idea on having a US distributor

    #11 4 years ago

    Sure, this is the prototype board in my F-14 Tomcat.
    I will take some more shots when I do my Laser Cue and Data East Checkpoint.

    I'll order 2 of these when Big Daddy starts selling them. Thanks for making these.

    #13 4 years ago

    Really great idea! Seems like a well done, well thought out product.

    Great solution for these older Williams games. I've seen melted wires between the transformer and power supply and I definitely don't want that to happen to any of my machines.

    #17 4 years ago

    Great news. Thanks.

    #18 4 years ago

    Just bought 2. After all the work I've put into my Space Shuttle (and soon PinBot) this is a small amount to pay for the security.

    #19 4 years ago

    Received and installed in my space shuttle. Works like a charm.

    Installation tips:
    Tighten up the connectors real good,
    don't forget the black wire clipped from the capacitor,
    and you'll need the instructions here: http://home.kpn.nl/p.koch3/laser_cue.htm and the pdf here: http://home.kpn.nl/p.koch3/Inkochnito_Bridge_Board.pdf.

    The pdf shows you the wire to connector mapping.

    I was able to install mine through the original rectifier holes. The new board lined up perfectly.

    #20 4 years ago

    Image please!

    #21 4 years ago

    Here's a pic of the board in place. It's really close to the side but that's with the original mounting holesWP_20140420_08_37_42_Pro.jpg

    Heres the before picWP_20140420_08_05_07_Pro.jpg

    #22 4 years ago

    I would have turned the board one quarter counter clockwise.
    Then the wires wouldn't be pressed against the side of the cabinet.
    And you can see the controll LED's more easely.
    Okee, you would need to drill 2 new holes, but it would be a better fit of the board.

    Nice job!

    #23 4 years ago

    Yeah, I'll do that. I'll need to remove the original mounts and get the correct length metal screws. I'll feel better when the rectifiers are flush to the metal.

    It's hard to see but there's .25 inch space between the wires at the side of the box. It's not as tight is it looks.

    I just fitted one of Peter's boards in my F14. It mounts just fine to the positions where the original bridge rectifiers were. The board overlaps *very* slightly with the flipper power board, but as it raised up quite high they're well clear of each other. Works a treat, cool way to replace the old bridges and capacitor and get the much needed 2 fuses done (I still need to tidy up the cabling a little).

    Buying some from Big Daddy today most likely. Got an F-14 and a millionaire I would like to fix.

    Everyone seems to like the bridge boards so hopefully they work well for me too!

    I ordered one of these from Big Daddy. Is it recommended to put thermal compound between the bridges and the sheetmetal in the back box? It looks like there was some used on the original BRs.

    #34 3 years ago

    I did not. My games spend only a fraction of the time on so I wasn't worried about it.

    #35 3 years ago
    Quoted from tonedef131:

    I isn't really nessesary, but it wouldn't hurt.
    My recommendation would be, if in the original situation compound has been used, use it again.
    But then again, it would not hurt to use it anyway.

    A Pin*Bot came in last month with its controlled illumination rectifier shorted. Pictures below tell you why to buy Peter's bridgeboard or at least add 2 fuses to the rectifiers in your early Williams game.......

    Yikes!

    #38 3 years ago

    It is the 2nd time I had a repair like this. The first one was also a Pin*Bot, a few years ago. In both cases the line fuse was stil intact....... Your house can burn down with accidents like this

    Does this still happen with all the correct fuses in the game (but without the bridges fused)? Just curious. I'd imagine the answer is yes

    #40 3 years ago

    Good question! Primary there was a 5A SB fuse installed in this (European 230VAC) game. According to the manual it should be a 4A SB. Still, secundary a current in excess of 50A in the 18VAC line can flow before the primary 4A line fuse trips..... And if someone replaced the primary line fuse for a 10A SB .......

    #41 3 years ago

    Thanks for the images Marco.
    I was looking for images to clearify my making the board.
    Really, an image says more than a thousand words...
    Can I use these images on my Bridge Board website?

    You are welcome Peter. Important to warn people about a potential danger in their game(s). No problem to use the images. I posted some more at pinside from the earlier incident, those I also posted at the Dutch NFV-forum a few years ago.

    It been a long time now.
    Time to update this posting a bit.

    I discovered there are some warnings due to Data East games.
    In some Data East games a motor is used.
    This motor runs on the 26Vac power taken from the bridge rectifier for the coils (white-red wires).
    Usually these extra two wires are connected to a 2-pin connector.
    When you remove the unneeded fuses for the bridge rectifiers, this motor will be left unfused.
    I recommend to reuse one fuse holder for the motor connector.
    Use a 2.5 Amp. fuse for the motor.
    It depends a bit on the type of motor used.

    The following games use extra motors:
    Batman (Batbar motor),
    Jurassic Park (T-Rex motor),
    Maverick (Paddle Wheel motor),
    Phantom of the Opera (Organ motor),
    Rocky & Bullwinkle (Saw motor),
    Star Trek 25th anniversary (Swinging Target & Transporter Special effect motor),
    Star Wars (Death Star, R2D2, Bar Target motor),
    Tales from the Crypt (up/down motor),
    The Who’s Tommy (The Mirror motor).

    Maybe someone with any of these games can tune in and measure the current each game motor is using.
    Then we can put the right fuse value with each game.

    The connected Bridge Board should look like this:

    Highly reccomend this board for older games.
    Have one in my Fire! Champagne.
    Brings piece of mind to old design.
