So I have this power supply for my Q*bert knocker: http://www.radioshack.com/product/index.jsp?productId=2049692&cp=&kw=power+30v&parentPage=search
The problem is that my knocker likes 3 amps. This thing only puts out 1 amp. This makes for a rather weak knock.
Does anyone know where to find a power supply with 3 amps at 30 volts? I've searched high and low with no luck.
Thank you!

Not exactly plug and play...
Is it hard to find original Q-bert power supplies? What about pinball machine power supplies? A lot of those used the same knocker didn't they?

Actually, it's in terms of the original game.
Q-Bert had a knocker in it. A knocker is a coil that sets off a piston that 'knocks' against a striker. In Q-Bert it's activated when the little guy falls off the pyramid. Kind of like he's hitting the bottom of the cab.

Now that I think about it. Might it be possible to actually use my original Q*bert power supply that is in the cabinet??
Right now I have all the fuses pulled from the board since it's mame'd. If I replace the fuses and run wires just from the 30v out and mount it just like I mounted the weaker power supply, it should work....shouldn't it? That would be the perfect voltage and amps right?
Am I off or am I not taking something into account here? Maybe the 30v out on the power board isn't constant since it would only trigger when the PCB tells it to. How would I overcome that?
Seems too easy.
Am I on to something here?
