Well the only tube that tested weak in the whole set (other than those in the VHF tuner I mentioned before), was the audio output. I swapped it for a stronger one, but I wasn't having any troubles with the sound. The 21CYP22A tests good (between 600-700 on all 3 guns) There were no bad tubes in the remote chassis like I expected. A lot of the tubes in this set look original and test very good, with the exception of the the fact that this has a replacement CRT this looks like a very low hour set. That in combination with the cracked CRT socket it had makes me wonder if they didn't replace the tube because someone banged the set from the back and broke the neck of the tube.

And I put the new CRT socket in. But I spent most of the night fixing my tube tester (Sencore TC28). I expected the problem to be dirty switches, which I took all apart and cleaned, but it was several bad solder joints on a circuit board. I have an older Sylvania tester from the early 50s I usually use, but it doesn't give settings for many of the newer tube types in this set.
