Tea AV 20B / AV20M is a very universal and stable tube, combining high gain, with a low output impedance. At a gain of 20, at only 11 Watts dissipation, there is no comparable directly heated tube, that offers a plate impedance of 3200 Ohm.
845 ... 211 Volts. 520 ... 500 Volts. 1200 ... 350 Volts. For lower supply the choke is recommended. 450 ... XNUMX Volt. (Lake Note4 for use with HV tubes)
As a lower signal tube, you can work at any required lower voltage, since you do not need to generate a maximum voltage swing.
As an output tube, use 450 Volts supply voltage for obtaining the maximum output power of 2.5 Watts.
