  • Description
  • Specifications

The 7Y4 is a full-wave vacuum rectifier tube designed to supply high-voltage direct current (DC) in power supply sections of AC-operated radio receivers and electronic equipment. Electrically comparable to octal-based rectifier tubes like the 6X5, it features a 6.3V filament rating drawing 500mA and uses an 8-pin lock-in (loctal) base enclosed in a T-9 glass envelope. Manufactured by companies including Sylvania, Philco, RCA, and GE, this tube provides reliable plate voltage rectification for mid-century vintage radio chassis and power supply restorations.
