I just got a Louis Electric Buster amp that runs a pair of 6L6's rated around 27W's. Not sure if the amp is biased cold to keep the wattage down or not. Regardless, it has a 5AR4 rectifier. I am wondering what are the best new / current issue 6L6 brands? I have a lot more experience with 6V6 tubes and have some preferences in that regard. The amp comes with a pair of JJ's or Ruby's. I like JJ's, but haven't ever loved them. They usually sound slightly hard and strident in the upper mids to me. But maybe 6L6's are different? How would you rank the following: JJ EH SED Winged "C" Tung Sol Reissues 6L6STR Ruby TAD I deliberately left Sovtek out since I usually find them the most harsh. I did a search, but there is SOOOO much information out there. Decided to try a new post. Thanks!
