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.

Would really appreciate if someone would take this on.
Would love to get the game 100%!

I created a new topic about the board and schematic at:

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?
Looks like the reproduction is going to happen:

Thanks KLOV members that were involved in making this happen!

Have dimensions.
Thanks
Quoted from Drewscruis:Do you still need the dimensions for this board? I have 1 on my bench for repair right now.

Still throwing the feelers out for an original sound amplifier.
