Hi. I am looking for a list of the warmest, smoothest and least fatiguing 12AX7 or electrically compatible equivalents, with low noise types scoring even higher.
Special emphasis should be on tubes that are still affordable.
I ended up buying a Hammond labeled GE long grey plate fat D getter 12ax7 (v2). I am combining it with a GE double mica support rod grey plate 5751 (v1, don't know what this one sounds like), and an RCA 6201 (v3).
I with be testing these against the stock red-label classic Psvanes.
