  • Description
  • Specifications

The 6SA7 and 6SA7GT are single-ended 8-pin octal pentagrid converter vacuum tubes introduced by RCA in the late 1930s. Designed for superheterodyne radio receivers, they combine the local oscillator and mixer functions in a single envelope. Utilizing an advanced single-ended construction, they eliminate the traditional top grid cap by routing the RF input grid directly to an octal base pin, simplifying receiver wiring. The standard 6SA7 features a metal envelope for integral shielding, while the 6SA7GT uses a compact T-9 glass envelope. Both operate on a 6.3V heater and fit standard 8-pin octal sockets. Available NOS and tested used.
