I'm really digging my Victorilux and I've got it sounding killer see tubes below! The only issue is the power tubes and I'm looking for a better 6l6 recommendation. I've tried two sets of Winged "C" and although they sound good they rattle a bit on certain notes...both pairs from different dealers. Tried JJ's...really liked the tone but those crapped out prematurely and didn't seem too reliable.
