I finally finished this set up and got it back in the cabinet!

Wound up replacing 2 tube sockets for the 12AU7 tubes, I have to wonder if all the tacked on caps I found when I started this project were someones (failed) vintage attempt to fix this same problem? They were most all in the same general area.

Other than that I found one bad i.f. tube that would short when warming up and kill the pic and sound intermittently.

Even though the 10BP4 checks good I was having a real hard time getting the picture set up right what with having to mess with an ion trap and the focus coil and trying to get it centered and no neck shadow.
I wound up putting in a 10FP4 tube that doesn't use an ion trap and was much easier to deal with.

The difference in brightness between the BP4 and the Aluminized FP4 is astounding!
