Yeah, we figured that's what's on the back cover there. Looks like its a bit loose, but I'll double check them just to be safe. Once I found this site and started reading about the tubes, I took them all out and put them back in. I'll admit I know less than nothing about this kind of stuff, but I love it. Is there a way to clean the connections, with rubbing alcohol or something like that?

In any case, thanks for the help. I'll continue to read around. You guys are pretty awesome. My dad builds custom arcade machines and tons of stuff like this-- but I haven't been into electronics since I was a kid.
