Hi,
Long story short, Looks like I have just sold my Atari Centipede cocktail, it had been moved recently and then put into storage, I have just powered on to test, and all seems well game plays fine, except now it has a noticable high pitched whine, after a bit of logical deduction it is coming from the games PCB, it is not from the CRT screen as I disconnected the CRT screen's power with the game running and the whine is still present.
Power supply has already been rebuilt by myself in the last three years, including replacment of the big blue.
Any ideas what could be causing it on the PCB and where to begin trouble shooting?
My hearing is good, but sadly not good enough to pinpoint exactly where it is comming from on the PCB.
Cheers.
