I just installed a flipper fidelity system in my no Good Gofers. I followed the instructions exactly (EDIT: no I didn't because I reversed a couple wires, DOHHH!) but when I powered the game on smoke came from a component right above where the the backbox speakers plug into the sound board. I can see the fried component but I don't know the name of it. (See pic of me pointing to it with a screwdriver) I immediately unplugged the game. I then unplugged the backbox speaker harness, subwoofer harness and powered back on. It then blew fuses F502 and F501. Can anyone please help me out as to what happened? Also, where would I be able to purchase the fried part without ordering online? Thanks

I've came to the conclusion that I plugged the volume control knob in backwards. Not too happy with myself right now... I'm going to order some new fuses and this kit from marco that contains the part i fried (TDA2030A) and a few other parts in case I might need them later.

Is there anything else I might have to replace?

Here's one more question. If I were to replace the 2 blown fuses (F502 and F501), then switch the backbox blown TDA2030A with the cabinet TDA2030A would I be able to still play the game but just not have any audio being pushed to the subwoofer? (swapping U5 and U6)

...and another head scratcher, I took out the 2 blown fuses and they are both 6.3a 250v. However, when I look in the manual it says these 2 fuses should be 2.5a 250v. Can anyone please confirm what amperage fuses are correct for F502 and F501?

So can anyone shed some light on if I should be on the lookout for other parts that might have fried? Or should this be as easy as replacing the fried sound amp and 2 fuses?

...and of course hooking up the speakers correctly this time...

Hi Michael,

Thanks for your input and the offer for me to send my board to you. I have done repairs in the past to my arcade boards so I can handle replacing the amp IC. I had one delivered overnight and am about to install it.

By no means was my original post meant to blame your products so I hope you didn't take it that way. Admittedly, it was my own fault for plugging in the volume control backwards.

I'll post back soon with my progress.

Thanks!

I replaced the fuses with the correct amperage and replaced the amp IC. Powered on the game and all is well now. WOW, these speakers sound great! The subwoofer is an incredible improvement over the stock woofer. Thank you Flipper Fidelity for a great product! I can definitely see myself upgrading my speakers in TSPP soon.

note to self...quit being dyslexic and quadruple check your wires!!

I'm sure it was just a perfect storm of wrong fuses, an old amp and my mistake of reversing wires. I'm just happy I didn't do any more damage and the game is up and running for the Christmas party.

Merry Christmas everyone.
