Maybe you should create one thread entitled 'Darren01274's 60-in-1/Jamma problem thread'? :)

how do you do that

I was kidding. Of course, it would work, but it would be way more trouble than it's worth.

What kind of speaker do you have hooked up? Is it amplified?

Post by: BobA on July 08, 2010, 10:36:50 am: They are usually AC powered but some come with an adapter or wall wart and these can be replaced by DC inside the cab if they are 12V. If not 12V then not worth the work to replace a 9V with a regulator from the 12V supply. The line power can be picked up at the same point as the AC for your arcade supply or PC supply depending on what you are using.
