Full-wave rectifier tubes are the heart and foundation of your amplifier's power supply. Poor rectification can adversely affect performance or severely shorten the life of your amplifier or tuner.

In Vintage H.H. Scott products these Full-Wave Vacuum Rectifier Tubes are typically used across the entire product range (Preamps, Integrated Amps, Tuners, and Receivers). Scott tuners and preamps typically use the 6X4, while the 5AR4 is popular in receivers and amplifiers.

Some later vintage H.H. Scott tube-types featured solid-state rectification.
