I have a burned through hole on my CPU board from a transistor that went way hot. There is even a burn mark on the sheet metal behind the board. Someone did a hack repair job, but it worked. Had a breakdown while rocking a great game(F-14, by the way) and all kinds of problems found including many fried transistors on the CPU. Decided to throw in the towel on the CPU and installed the Rottendog boards. I have very muted sound. If you get close, you can hear something, but that's it.
Anyone have the same problem?

I'll post a picture of the old CPU for kicks.

I heard that if someone has already done a hack job, they won't touch them. The guy that did the hack job repair was very heavy handed with the solder. It's a bad mess. Besides, already have the Rottendog boards now.

Still no sound. Doubled checked sound board connection pins. Didn't remove board, used mirror to see, but just for my own piece of mind I'll pull the board recheck everything.
Part two, I know this is off topic a little, but I have also been rebuilding all snubber boards with the information found here at Pinside. Found two fried resistors on two different boards. Aftermarket ones not being made anymore, but from what I found here, might as well rebuild them all. One thing that has confused me. Color code shows 470 ohm resistor, but everyone here is saying 150 ohm. Also upgrading the caps. with 3000 hr. ones instead of the standard 2000 hr. Jameco here in the bay area has everything. Two diodes, one resistor, and one cap. Relays are not being touched. Should I replace them too? Has anyone had a problem with the relays?

Here's a picture of the fried resistors...

Also has anyone seen a C-11232 snubber WITHOUT a resistor? Here is a picture of a C-11232 snubber without the resistor. But if you look close, there are heat markers on the board like one was there. Very weird.

Any input?

Yes, I have been reading all snubber posts and it is a C-11232. I have two C-11232-1 with just a relay and a diode. Color bands on a non-burned resistor is yellow, violet, brown, gold. That means 470 ohms. This is why I have confusion. I followed the values posted on a picture in the snubber post.
One 150 ohm resistor, two 1N4004 diodes, and one 100u, 100v cap.

Here is a picture of a board before rebuilding. Note the resistor on the board. Looking at the color code shows 470 ohm. You can under stand my confusion after everything read here at Pinside. Plus parts ordered from Jameco. Two 1N4004 diodes, one 150 ohm resistor, and one 100u 100v cap. Note the double size of the cap. being 3000 hr. Standard ones are 2000 hr.

Started into this unless someone has a disagreement with my parts shown. Any input here would be great, Thanks.
