I've put a better 6SL7 and will need to know if I have to change the resistance of the cathode has more gain and I have to go up less volume
the concept is good or parallel would have to change
on the other hand I put resistors in the cathodes of independent EL34 12w 820ohn
Why not just build the amp as is and build a separate preamp if you need one. If you do end up needing a preamp you can swap them out if you want to try something different.
Now that I think of it,you are probably right because this is using IT coupling and EL34 are relatively easy to drive and then he can just implement an extra stage later if he feels he needs more gain in the early stage.
I feel very good the circuit I will make and tell you my experience
Thank you very much for the help
