Construction Structure of a modern low-power triode vacuum tube.
At fields around this point, the device operates similar to a triode.
Beam power tubes can be connected as triodes for improved audio tonal quality but in triode mode deliver significantly reduced power output.
For example, the ECC83 (equivalent to the 12AX7) is a 6.3V (E) double triode (CC) with a miniature base (8).
From here, a circuit designer can choose the operating point of the particular triode.
He would later go on to help refine the triode vacuum tube.
