Interesting tube that works both as an amplifier and rectifier...
That 300B is a Western Electric (design) triode power tube. Designed for audio output. Almost any audio output tube "could" be used as a rectifier. It was Western Electric design practice to use same tube as audio output and also as rectifier.
