Anyone used a 6SJ7 in a preamp?
Hello all. I'm working on a new amp loosely based on a Rt.66 idea, pentode pre into tone control into phase inverter into UL output stage, no feedback. I will be using a Dynaco ST70 OT and Mullard EL34's, and was considering a 6SL7 PI and an octal pentode.  
 
I have a metal NOS 6SJ7 pentode, has anyone used one of these in a guitar preamp, and do you have comments on tone or microphonics? Thanks!
