I burned out 2 new 9AU7s before I figured this out. I bent the contacts in the socket back in a way that it worked (only after burning out another 9AU7 testing it out). But tonight I turned it on and the same problem reoccured and took out my 4th 9AU7. This time I kind of screwed up the socket worse trying to bend it again so it would make a tighter fit. I finally jammed a bit of wire in the socket along with the pin of the tube not making contact to make a tighter fit, and this seems to work. But I'd like to come up with a better solution? But for now I'm not moving that tube until I get more, it being my last 9AU7.

Your set is the earliest model of that series. I only saw one that used the 2EN5, horizontal AFC tube. The rest, all seemed to use dual selenium diodes.
It's been ages, since I worked on one of those dogs.
