Hi there....from sound practises fall 1994....factors determing tube life...quote <...An unstable heater voltage is extremely detrimental to tube life.......the effect of plate overload of 50% reduces tube life by 25%.......I agree with Frank........run tubes at their bogey heater values and operate all tubes well within their tolerance ratings. Simple.

Hi,
Ah, well...
Guess we should all be very grateful no one chipped in with references to the French LED mag and their tube "designs" so far.

Ii am running an 6ag5 penthode in triode mode on 12 volt. For as far as i can judje from my scope, there isn't that mucht distortion and it sounds very well in the lowest octaves.
I am going to wrap it up into a small package. The 6dB gain makes it perfect for adding tube sound to transistorized sets!
I'm not sure, but could it be that the enoemous distance between anode and cathode make this a good candidate. It runs cool as well in the "space grid charge" mode. reversing the grids...
