VTV (Vacuum Tube Valley) did a shoot out a while back...google it or might be on audio asylum. I cannot remember where I read it. Might be useful.
EL34 quad for LM Audio 211
Driving a pair of Spendor 3/5 R's w/ the LM. A very enjoyable combination btw. The Genalex KT-77 seems to have earned a good following lately. I want to play to the strength of my speakers, which is the midrange. Using new production Mullard/Tungsol for (12ax7/12au7)input tubes. Cheers -Don
