On the Dodd elp what do the 2 tubes do? which one is output? and which is the other? just got in a single amperex 7308 and want it on output duty... Thanks

nevermind, both tubes are outputs per gary a few minutes ago... I heard someone say one was output and the other was something else... maybe i read wrong, dunno... so i'll look for another 7308 later to make a pair...
