The 6922 is a miniature nine-pin medium gain dual triode vacuum tube. It is distinguished by its very high transconductance, mostly the result of its frame grid construction. Versions of the tube are named ECC88, E88CC, 6DJ82, E188CC, CV4108, 7308, 6N1P and 6N23P. Although not originally designed for the purpose, it became popular in hi-fi audio amplifiers.
