    I’m in need of the following sound amplifier for my Chicago Coin Mini Baseball game.
    Please help me get this game 100% up and running.
    Thanks in advance!

    Another bump.

    Are you missing the whole board, or is it just not working? If you have it and it doesn't work, the most likely problem would be bad capacitors.

    Unfortunately when I bought the game the sound amplifier was missing.

    Beginning of the weekend bump.

    #9 59 days ago

    I'm curious if anyone has considered reproducing these boards and what the demand might be. Judging from the schematic in the manual it shouldn't be that hard to lay out a board and have it made. That assumes that there are modern equivalents for all the parts used.

    From what I can tell in my fuzzy schematic copy it lists:
    - DA1704 diodes
    - X16A5332 transistors
    - X1FA5332 transistor
    - URL1D6005 op amp (?)

    These may be Chicago Coin part numbers but a little detective work might reveal more standardized part numbers that can be cross referenced to equivalent parts.

    The rest of the parts appear to be generic resistors and capacitors.

    Might have a person that would be willing to reproduce this possibly.
    I'm in need of the exterior dimensions of the audio PCB for anyone that has one please.

    #18 21 days ago

    Anybody help me with this?

    #19 21 days ago

    My sound board is at a friends house right now for the capacitor repairs. I'll get the dimensions to you tomorrow.

    Any luck on getting to your friends house to get those dimensions by chance?

    #21 19 days ago

    Bump.
    Still wanting to reach out to see if someone has the original sound amplifier before I have someone making a repo.

    #22 17 days ago

    Looks like the reproduction is going to happen:
