The 6J5 (1/2 of a 6SN7) does have way enough gain for the application. The operating point on the plate curves is good. The right brand of 6J5 should sound excellent.My notes over the years have shown higher gain front-ends of amps sound better with the right high gain tubes. I am not opposed to cross over to the 'sinful dark side' using a pentode preamp tube either. The stellar performing H&K Citation II and Marantz 8B that use pentode preamp tubes come to mind.
I like the Tung Sol 6SL7 round plate as a preamp tube is all. Nothing wrong with a 6J5 tube as seen on the paper specs. Being the 6J5 is 1/2 of a 6SN7 and I do not like the sound of many 6SN7s, simply choose a great sounding 6J5. Perhaps a Sylvania 6J5GT with that same plate as my favorite Sylvania 6SN7GTA exists.
Bottom line is IMO the brand of tubes make or break an amp.
Edit- I remember using a Sylvania 6J5GT with a metal base and black round plate. That is a good sounding tube!
