Don't ya know that those folks back in the 50's would have never imagined anyone would be attempting to rebuild such a tube... especially so many years down the road!

The 19VP22 tube that followed... is it a closer sibling to the 15G, or to the 21AXP?

The 19V is closer to the 21AX. The 19V was the first tube to use photo deposition of phosphor dots directly to the inside face of the tube.


Kevin, Georgeous screen shot of your 21AX. I would want to save that tube too. The color saturation is fantastic. I hope my CTC4 looks that good when I get around to restoring it.
