The 5U4 is a common full-wave rectifier tube used in power supplies to convert alternating current to direct current in. Its twin-diode design uses a shared cathode and two anodes to convert both halves of the AC cycle. Rectifiers like the 5U4 are sometimes overlooked by audiophiles, but like power and signal tubes, they can greatly influence the sound of a tube amplifier.
