Frontier1,
I have a Canary CA-339 MKII amp and went through the same thing a few months back. I ended up with Psvane T-series 300B and CV-181 (6SN7). I purchased mine from Grant Fidelity (Rachel). I just love these tubes and glad I made the move. Now Psvane has a newer version of the T-series. I can't comment on those. My previous tubes was EH Gold Grid. They where excellent tubes but not on the same level as the Psvane IMHO. Now of course the Psvane cost a lot more.
Good luck on your search.
