16GP4 Search

[Ampico-kid]

I'm almost ready to start restoring my '51 Zenith Porthole. This set uses a 16GP4 crt and presently has a booster attached. I checked the tube with my CRT testing unit and the meter remains motionless at the bottom of the scale, which is not a good sign.

I'm now thinking I should be looking for a replacement (yeah me and the rest of the early tv collecting world).

This seems like a pretty popular tube, and unfortunately I guess it's also in very short supply.

Anyone have any leads??

It would be much appreciated.

Thanks!
Bob.
