Semiremote-Cutoff Pentode
Manufacturing years ~ 1951 through 1952.
The 6SG7GT Vacuum tube is a glass type. It features high transconductance with low grid-plate
capacitance. The 6SG7GT tube is suitable for frequencies up to 18 MHz (approximately.).
Two separate cathode terminals enable the 6SG7GT tube input and output circuits to effectively be
isolated from each other. The 6SG7GT requires an octal socket and may be mounted in any position.
