Donny, I would be interested in buying the rest of those small 12v supplys if you have any more of them. PM me with what you have.

Those 24v ones would work well for QBerts sound section.

I still have a bunch of those left, i also have some of those 10In lcd screens left, pm me with offer for the small 12vs

Tell you what, count up how many you have and figure up what it will cost to ship them to 20650. I have to factor in shipping cost to be able to make an offer on them.
The large flat rate box might be our friend on this one.

Is the Price too high???

I have a bunch of these and want to move them, make offer if you think its to high

Again 7 for 50$ plus shipping. 7 bucks a peice if you buy 7
 
You could use it to power the 30v line on a qbert. Basically you would leave your original power supply in for the other voltages, pull the fuse for the 30v circuit and remove the pin for the 30v output of the power supply. Connect that wire to the new power supply and tie the ground in with the others.
I would verify the output of these power supplys before hooking up the sound board...just in case. I always test the power supply outputs prior to hooking up the sound board and main pcb when im testing a QB power supply. Bad power on a QB causes a chain reaction of component failures and can be quite expensive to fix.
But yeah, if these power supplys put out enough juice they should be a good solution to the common 30v failure on these. The're cheap enough, worth giving it a try.
 
I believe 24VDC will work in the game. I use a separate switched 24VDC for the Gottlieb sound boards when they are on my test bench. The switch on this one is a great plus. Also gives better headroom from the max supply voltage for the audio amp. A lot of folks recommend lowering the 30VDC output to the sound board.

There is no doubt that the LM379 will function at 24v. The question would be if that supply has enough kick to power it and the knocker. Im sure it probably would but without testing it I wouldnt say yes or no.
