Frenchy,
It looks a lot like my CTC 11 also.
Below is what I found on the CRT. Is this kosher or should I be doing something else?
The cap on the 3A3 was corroded fast to the tube. I will have to replace the cap. Half way through testing the tubes and only found a bad 12BY7 so far. The 6GH8's are next.
