Commercial ITT tube, thin film, autogated, roughly omni 7 equivalent, but still technicly a commercial tube.
Gain knob is a little funny, when turning it will briefly jump up max gain, then back to the correct set gain. If it gets worse, obviously I'll warranty the battery pack out, but for now it's certainly workable, if a little odd.
