Only thing to be careful of, is that the TungSol and EH don't work nicely in Cathode Follower positions. So i tend to use Chinese or JJ 12AX7 tubes in the Cathode Follower since they can handle the Heater to Cathode voltage fine.

Yup that's a solution to it, which i have used a bunch of times Just thought i'd mention the CF issues for those who have production amps without elevated heaters though
