SUch tubes do exist. They have been spoken abut here. something like "19gvp22" or so. I think they are ALL R.E. and maybe even matrix. I expect the cathodes would be VERY heavily evaporated and thick. Not sure if they would have that "Magic color" of a 21FB or 21AX but they would likely last as long as a CCII tube!! Probably cost the taxpayers over a grand each new, too.
