Howdy all, I'm sure this topic exists somewhere in the depths of this forum so I apologize in advance. I'm picking up a used TR. The guy I'm buying it from (a good friend that I trust) tells me it needs new tubes and to be biased. He told me to let him know what kind of tubes I want and he will order them and get it set up. I have a Super Reverb now with JJ's in it, but there is very little headroom. I know that is probably more to do with the amp than the tubes. At least thats what I've been told. I am hoping some kind folks could chime in and tell me what they recommend or what they use in a TR. As always thanks.
