I've got a Bally/Midway Gaplus, and seem to be having problems with my power supply. It's only putting out about 5.5V on the 12V line. Gaplus works fine in it, as does a 48-in-1 board (via a JAMMA cabinet adapter), but some boards have no sound (Black Tiger) and some are horribly distorted (Crazy Kong). Just wondering what I should check first, or if there's something that normally causes this problem. I'll include pics of both the transformer block, and the regulator board (which is an MCR style, 90412-D000) Thanks in advance!

(oh, and if anyone notices, yes, there is a blown fuse, the right-most one in that little 4-fuse block. I had the problem before it blew, and it's only going to the coin door lights, which I don't need anyway, so I haven't bothered to replace it)
