6A4, 46 and 47...excellent sound tubes !!!!
I'm currently testing the tubes 46, 47 and 6A4 in single ended triode and pentode modes.
I built a prototype in an aluminum tray.
I used a cardboard open baffle with a full range Trusonic 80FR and a Foster horn.
These old tubes play very well, watch the videos:
