I've got a Joust that's not working, and giving the 1-3-1 RAM error. The 12V is out on the power supply... or at least, it's out when the boards are all plugged up. When I remove the load from it, the 12V line goes up to about 28V, but under load it measures roughly zero. I've replaced the 2N3055. I don't think the bridge rectifier for that line is bad, because I'm measuring about 29VDC at its + terminal. I'm suspecting the 723 voltage regulator now, but wanted to see if anyone else had ideas... thanks in advance.
