FWIW, as I recall the SFL 1 you can use either 6922 or 12AX7a's ( I think you must make a minor adjustment in the preamp). If that is correct you have a lot of options depending on what tone you want. Best to listen to what you have carfully, then come back later when you know what tonal changes you want to effect by changing tubes (or tube types). Jobes Tube lore is fine, but it only covers NOS tubes. For less expensive new production tubes you'll have to do some online research. They have been discussed to death.
tube character with pre-amp
As a new and excited tube pre-amp owner I wonder if a few can give ideas of tubes that can one day be explored in my Sonic Frontiers, I know little to nothing of what tubes have what sonic character so I am asking for opinions, I will say I am sorry if this has been hashed out to death here. I may also want to add that I am using Innersound Eros Electrostat Hybrids and like the sound, at increased levels the highs can start to fatigue although I am not sure if this is blamed by my Rotel Pre, my room or both and then some.....thanks
