Throwing out a request for advice. Attached are some pictures of the biggest $1 tubes I have acquired.

From left to right:
"super 6BG6GA" (not $1!)
GE 19BG6GA
Raytheon 19BG6GA
21EX6
36LW6

I was wondering if you knew or had tested or had a guess at which could work in triode service for decent power, i.e. which ones might work at above the rated screen maximum voltage if triode strapped.

I'll quote you their published screen ratings to save you time.

19BG6GA: 350V, 3.2W
21EX6: 195V, 3.5W
36LW6: 280V, 7.0W
