This is my Wonka set up for sound. It’s worked well for over a year or two. Recently, the sound on the entire machine will intermittently cut out; come back on for a 10-15 seconds then cut out for a 10-15 seconds. It will keep cycling like that. If I unhook the external sub input wires, by disconnecting the alligator clips, the problem goes away (but then of course I don’t have subwoofer sound). In addition, I’m not sure if this is supposed to happen - but when I was unhooking the alligator clips while the game and the amplifier/subwoofer were on, there was enough current in the wire to spark (as I was physically removing the wire from the terminal). So right now, just playing the machine stock, and would like to hook the subwoofer back up and have it work correctly. I have tried several times and it keeps on doing it cycle on and off thing. Any advice would be appreciated!

I was thinking that might be the case. Any idea how to test that? In the meantime, I’m going to take the amp apart and look at it.

Thanks! I agree. I’ll post the process and solution.

The amp board looks pretty good I guess. There is some corrosion on the underside that I cleaned up. I’ll reinstall it see if it helped at all.

I don’t know if it made a difference or not. I didn’t keep it on long enough to see. Usually the problem of cycling on/off sound starts after about 3 to 4 minutes of play. Reason I didn’t leave it on long enough is because even with the amp off, the sound coming from the cabinet speakers up top is scratchy when the alligator clips are attached. If I detach them, then the scratchy sound goes away. makes me question the connection at the alligator clips and connection point? There’s good connection and the terminals appear clean. Hmmmmm

Definitely appreciate the info. I have ordered the high-low adapter. The amp is 12v5a. I hope the pic helps answer.

@mbwalker. Sorry about late response. I have from the wall a two prong power cord that goes to a AC adapter, then into the 12 V5A labeled port on the amplifier. Input into the amplifier is direct connection from the speaker terminal. Speaker terminal two alligator clip RCA cables that I stripped, then input RCA cable adapters into the amplifier. output from amplifier goes directly left (red), left (black) to the speaker. When I get a replacement amp, they’re only 40 bucks, I will look for one with a three prong. But since it’s not completely useless, and the problem starts 3 to 4 minutes in to using it, I’m gonna try the adapter first and see if it makes a difference. Thank you for the information, truly appreciate. Like the diagram that you put together for me

Appreciate you guys on this thread. I’ll keep it updated when I get the parts.

This fixed the entire problem. The sound System performs better than it ever has now. No cutting out, no scratchy, bass sounds really good. Thank you so much!!!
