metal, with a ceramic base. Triodes and a few tetrodes and pentodes were made; nuvistor tetrodes were taller than triodes. Nuvistors are among the highest-performing

The later vacuum triodes allowed the signal to be amplified to any desired level, typically by feeding the amplified output of one triode into the grid of

6SN7 is a dual triode vacuum tube with an eight-pin octal base. It provides a medium gain (20 dB). The 6SN7 is basically two 6J5 triodes in one envelope
