38, 38 A, 38 B
#14

For a power output tube in a battery set the 19 is hard to beat. In the 30's it was a popular tube to build low power portable battery powered ham transmitters, back then AC current wasn't everywhere yet. Philco used these https://frank.pocnet.net/sheets/201/1/1E7G.pdf but as you can see it's output is much lower.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
