A Set I Haven't Seen Discussed

[John Folsom]

I concur with Charles. I have seen 3 of the 19VP22 CRTs, and all had good vacuum. While the 19VP22 has the same type ultor welded flange that the 15GP22 does, it seems that they were not as prone to leaks as the 15GP22. Maybe Hytron had a better manufacturing process.

Urban legend says that there were premature failure issues with the 19VP22, supposedly due to internal arcing. I have not seen this rumor substantiated in print. But for whatever reason, the 19VP22 was produced for only a short time, and only used in the 1954-55 model sets.

If anyone has any additional information on the 19VP22, please share it with us.
