21FBP22 Replacement
Sorry for the late reply, I've been working on my own computer system hard drive diaster since the 1st of the month. Lost all my Healey and 21CT55 photos so can feel Wain's disappointment with the CTC5. I replaced the 21AXP22s with 21FBP22s in my CTC4 and CTC2B in early 1960. They are both mounted the same with four struts running from the yoke assembly to the cabinet front structure. The 21FBP22's glass envelopes were wider than the metal coned 21AXP22s so the plastic insulating shroud had to be cut away from its front mask bell and the struts had to be lengthened and remounted to the cabinet's front wooden structure. I used screw-eyes screwed directly into the wooden front. Since I'm not a restorer, this hack was fine with me
I realize the CTC5 uses the plastic shroud to mount the yoke assembly and support the CRT. If it can't be modified maybe the strut and screw eye scheme will work for you. What do 21FB's sell for these days especially the rare-earth A version? Replacing the 21AX's with the 21FBs is the way to go, you won't be sorry..........Tom
