Wayne,

I have been working on my CTC 5 and have a few questions. I was earlier plagued by bad CRT tracking which made it difficult to get a good greyscale. On my B&K 467 CRT tester, the 21AXP22A red gun emission was poor. It had been like that since I picked up this set seven years ago.

I was reluctant to rejuvenate the gun as I felt some emission was better than none. I however last weekend took the gamble and gave it a good blast and low and behold it woke up! The CRT tracks well, the emission tests good and importantly I now can get a consistent greyscale.

The only thing now is the picture is dim! I have a 1961 CTC-11 with a 70's CRT replacement and it is pretty bright.

What is the condition of your 21AXP22A? And how to you find the relative brightness say compared to the all glass CRT you had in your CTC 5 before the 21AXP22A?
