    I have a Twin Rifle gun game that has a sound board not working. I'm going to replace all the capacitors to see if that fixes it but it has one that I have no idea what the voltage and capacitance is. The markings are as follows:

    EBS
    6951
    100/25
    23D84
    669A08

    I googled those numbers but didn't find anything. If I were to guess I would say the 100/25 is 100uf 25v but that is just a wild guess. Any help would be appreciated.

    Here is a pic. Sorry its a little blurry. It's the best my cell phone can do. It's the big silver one in question.

    Yes, the Chicago Coin Twin Rifle. There is 2 small sound boards for the gun fire located under the guns.

    Did www.mouser.com turn anything up?

    I put the numbers in a mouser search and nothing came up. I checked great plains electronics as well.

    Here is the flyer. You can see at the bottom it says:

    I have a schematic but it doesn't have anything about the sound boards on it.

    Edit: I think there is a manual for the game but I don't have one. Maybe the schematic for the boards is in it. Marco has the manual. I guess I'll order one if I can't identify the cap.

    100uF 25v

    Caps i find on old Bally sound boards are marked like that.

    Got an ESR meter? You could always just test them and get results.

    +1

    Yep if you squint and look at the writing on the top part of that pic you can make out 100/25

    I don't have one. But barakandl confirmed what I was guessing. 100uf 25v. Thanks all for the help!

    I found a schematic on line that has the coils, switches and bridges, but nothing that looks like a sound card. Must be a separate schematic for that. Interesting stuff.
