Well, you can NOT substitute a 6AX8 for a 6JU7. I was looking at the voltages at the G/Y, B/Y R/Y amp tubes and they were just wacky. So I looked up the 6AX8 in the RCA tube book I have and it turns out it is not even a dual triode like the 6GU7, it's a pentode. I can't find the book I was looking at before, I do remember buying them about a year ago because I found them cheap and I remembered reading that they would exchange with 6GU7s. Anyway, I had 2 used 6GU7s and I put them in instead, and they work great.

No problem at all with not enough red, I just have the red screen control a bit higher than the others. I think also it had started reading really low due to loose wires in the tube base. I am now having problems with the socket in my color crt tester, so I can't test it to see if it went back up after I resoldered the base, but seeing it isn't a problem, I guess it doesn't matter. I only wish I had thought to glue the base to the tube when I put it back on, it works, but is loose, but then I really don't want to take it off again.

It still needs plenty work, the wire fuse for the tube heaters burned out, and I just twisted it together so I could continue to work on the set, but should replace it. The convergence needs to be done, and this will be my first attempt at doing that. And I need to change the electrolytics in the power supply/amp at the very least to get the stereo to work. And one of the legs is broken off.
