[Milsurplus] Wireless Set 19 Amplifier etc

[Bry Carling]

I love those old, white ceramic based 807s. Fond memories of them in 19 sets 
as a teenager... I don't remember seening an ATS25. It's also listed as equivelaent to the 5B-
250M.  I think they are also electrically equivalent to the 5B-254M which is a loctal based 
version we used in a homebrew transmitter back around 1963, with a 6AG7 osc.

We used to find those valves as military surplus in England in the 1960s.
