I've always been interested in the 815 based 50 watt transmetter that showed up in QST and the ARRL handbooks just before WWII. The 815 is a dual "beam" tube designed for UHF (150 MHz in 1940). I'm starting to plan a tramsmitter using an 815 as a push-pull final (as shown in Feb '41 QST) driven by a 6L6 tri-tet oscillator such as used by Millen in his 6L6-807 rack moount transmitter.
