Pa <25W, Ik <260mA, gm 20mA/V
Designed for low-voltage, high power audio output. The 15W heater power aids the good emission.
Can achieve 25W output in class AB with 200V supply for anode and screen; requires only 20V rms drive to the grids for full power output.
Despite potentially being a better performance tube than the popular KT66, a 6.3V heater version of the KT55 would have required some 2.5A compared with the 1.3A for the KT66.
