Used up aired out 16AP4 on eBay

[Eric H]

A junk CRT on eBay for $99.
Note the white getter and the dark area on the neck.

This tube was probably used up when it was replaced and it went to air sometime in the following fifty years after that.

Edit, I see a 1957 date code on the base cap, it must have been a replacement tube itself.

I sent the seller a note that it was used and bad, we'll see what they say or do.
