6SK7
The 6SK7 is a remote-cutoff pentode in a metal enclosure, developed for use as high-gain radio frequency (RF) and intermediate frequency (IF) amplifiers in radio receivers. Because of its cutoff characteristic, it can handle high signal levels without cross modulation or distortion. It is also suitable for receivers with automatic gain control (AGC). Pinout at seen from the bottom.
