But test low (emission) as i say here http://audiokarma.org/forums/showthread.php?t=583374 Still don't know if this testing is ok for this type of tube, as i only ave one pair, i cannot compare... PS: I just rolled them in my amp , and they really smooths high frequencies compared to Sylvania's GTA GTB. Last edited: Nov 27, 2014
