The PX25 Triode

PX25. The PX25 is a British tube and is sort of the English answer to the 2A3 with about twice its power. Tube data for the PX25 can be found here.

A comparison of some Triode contemporaries: the modern production Czech KR PX25, the Russian Genelex Gold Lion 300B, Russian Sovtek 2A3, and finally a 1930's USA RCA/Cunningham ST 45. An audio Baskin Robbins of Triode flavors.
