Thanks all! I did clean all sockets using a small dental brush and Deoxit D5. I just sprayed a little on the brush, cleaned each socket pin, and let it dry while I worked on other stuff. Actually, everything had over a week to dry. For the tubes themselves, all of the original tubes but one tested bad, and I ended up replacing them. The 7B7 had one pin that was visibly dirty so just went over all the pins very very lightly with a small piece of dry Scotch Brite pad. Seemed to do the trick!
