You would have better luck finding a gold nugget in your backyard !
Try these guys - https://www.chimeunit.com/
Yeah i know, thought it was worth a try (the sound of the crickets was deafening!!) . I'll just give the game back without a chime box.. not my problem i just told them i'd TRY to find one but no promises. I have one in a Jacks Open i was thinking of scrapping but i've just had an offer from someone to buy the machine so it's staying with the machine!
It pisses me off that some people pull them out of the machines in the first place, and knowing there are guys out there hoarding these things, i know of two guys not far from me that have a couple each and won't sell.. and i KNOW they'll never use them!!
oh well such is life .. rant over, as i said not my problem once they have their Jet Spin back fully working minus the chimes.
