6CG8A Hytron Triode-Pentode Vacuum Tube - NEW OLD STOCK - TESTED
This listing is for a high-quality Hytron 6CG8A Triode-Pentode vacuum tube. The 6CG8A is a versatile miniature 9-pin tube, featuring two distinct sections: a triode and a sharp-cutoff pentode housed in a single glass envelope. This combination made it highly popular in vintage television receivers where it was typically utilized as a combined VHF oscillator and mixer stage. Its design was optimized for IF (Intermediate Frequency) circuits in the 40MHz range.
Manufactured by Hytron, a respected American tube company known for quality production, this tube represents New Old Stock (NOS) and is a great find for collectors, restorers, or anyone needing a reliable replacement for vintage TV sets or classic radio equipment. The 6CG8A's robust performance in high-frequency applications makes it an essential component for maintaining the authenticity and functionality of period electronics.
