Hi,You can plug in any 6sn7 gt,gtb,gta wgt,w,& A / 5692/VT 231 or 6sL7 / 6SU7. without any problem with your amp or preamp,I been doing these any time and I even have an adapter for 12AX7/12AU7/12AT7/12BZ7 to the 8BD BASE socket and they work fine if you are only looking for sound..
6sn7 or 6sl7
I have an Almarro A318-B and would like to swap out one of the preamp tubes, but I cannot decide which one would have the greatest affect on the sound. The Almarro uses a 6sl7 as the input tube and the 6sn7 as an "anode follower" (I'm not sure what that is?). I can only afford to do one now, so hence my dilemma. I have three different 6sn7's at the moment with the following characteristics: RCA 6SN7-GTB that has a detailed but lush presentation; Electro-Harmonix that has a very detailed and airy sound, but is a little flat and edgy, and last is the stock Russian 6H8C that images very well but has limited frequency extension. I have only used the stock Russian 6sl7 (6H9C) with all of these because that is the only one I have.
Any insight would be much appreciated.
Thanks!!
