19AP4 Needed

[GaryK]

I tested my old 19AP4 before I started restoring my 1951 Zenith porthole TV. It tested in the low end of "good" with low but reasonable "cutoff". Now that I have the chassis working and put the tube back on I see it is very dim. I re-tested the tube and now it tests in the "bad" section with minimal cutoff. Either I was hallucinating when I first tested the tube or after it cooled down from the first test it gave up the ghost. Anyhow I don't want to rejuve it with my B&K and I don't have a beam builder so I am going to put the set back together for now and see if I can find a replacement 19AP4.

If you have one you would like to sell my email is

Thanks! Gary

UPDATE- I discovered that although the tube i have is somewhat weak it is watchable to the point I can demonstrate the TV to friends who are curious. As I reviewed my finances at this time I cannot afford to buy a replacement tube but thanks to all who responded on my behalf.
