I am looking for a 14cp4 picture tube for a 1952 fada tv. Found this tv few years ago and finally got around to checking it out. Unfortunately tube test bad. No emissions and G1 to cathode short that won't go away. Would consider a compatible one, if there are any, as long as I wouldn't have to alter the circuit.

I have a 14rp4 if its interchangeable with yours I don't know.
