Not sure if I can ask this or not moderators can remove this if need be. I am in he process of buying 4 new 6l6GC's for my Fender amp. Are there any that I should stay away from I hear Sovtek thrown around a lot as good ones I hear Groove Tube good and bad. Also looking for good distributors I really want to avoid "the bay" and I am sure there are sponsors here. RCA's,GE's,JJ's ?? Thanks for any help
