Rectifier - Full Wave ·Rectifier-Rectifier
Directly heated full-wave high-vacuum rectifier electrically related to the 5U4 family but using a different socket arrangement. Its heavy five-volt filament supports substantial power-supply current.
Mesh full-wave rectifier electrically identical to 5U4G apart from socket. The supplied Emission Labs sheet was read for filament data, maximum ratings, representative operating points, gm/rp/mu, output conditions, capacitances, and rectifier filter conditions as applicable.
Medium-shell UX 4-contact
