I have a few of my Modern machines stop doing things like no audio or one of two the jackpot circuits won't send the signal to the payout motor .

I think the manufacturers plan for the machines to work right for maybe Five years (the machines are by law retired after Two years) .

Things like a capacitor or op amp i.c. go bad and things happen .

Then you have to learn how to troubleshoot without schematics and know how to troubleshoot logic circuits and multimeter and oscilloscopes .

That's why some of our members like the 1970's and older Gravity feed machines aka "Vintage" .Very simple mechanical knowledge needed .

Anyone want to adopt my Modern machines all you have to do is come to Monterey, California and choose which one and only $50 to $70 adoption fee

Oh, the Moderns that have problems are my Thunderbirds II and Maharaja both have a Audio problem and the one with the payout problem Cobra, Space Adventurer.

Now back to the Thread in progress. . . . and ginger snaps cookies .
