IIRC. A fresh tube will fool you with a fix but soon gives problems
again. Easy to change with the right socket. Just dike them apart
& pull one pin at a time like teeth.

The two tubes in the red rectangle? The one which I changed twice, is V202, the symptom was loss of horizontal lock. I changed it first in 2014, and again in 2019. The tube I changed was a replacement RCA tube, which had been changed by an RCA service center some time in the 70s. The TV was very low hours when I got it. I should order a couple sockets to have on hand, I would never have suspected the socket itself could go bad. V202 seems to run quite hot, but since the set works properly I just sort of assumed that must be normal.
