The 6W6GT is a beam tetrode with an an ode dissipation of 7 Watts. The design use was for vertical amplification in 525 line 30 frame TV receivers. The alternate use was as a Class A audio amplifier. At 10% THD the 6W6GT could produce 3.8 Watts.
The xW6GT family also included the 12W6GT with a 12.6 Volt heater and 25W6GT with a 300 mAheater running at 25 Volts.
