Hello Squirrel Boy I just wanted to say thanks for the info I'll be keeping an eye out on those links. Unfortunately the tech had told me that the tube is just done, the rejuvenation didn't help at all. In fact the emissions from the gun actually got worse. There is no direct replacement because the heater in this 19ABP4 runs at 2.68 volts; the only 19" tube to run at such low voltage. Unfortunately the Philco Town and Country is just so cramped inside that it'd even be difficult to find a place to wire in a transformer to use a different tube. Once again thanks for your response and for your help.
