aka the classic behringer marketing glowing valve.
i always find it funny that a company would go out of their way to make the valve visible and still put a small bulb behind the valve, to make it look like its on.
technically if a 12ax7 lights up like that, it would be for the split second when it explodes.
i just feel they are giving the new generation a wrong impression of valves.
i wonder when will the t-87 be coming out ?
