Anyone have experience running a 12A*7 tube on +/- 15V? Seems easy enough to try it out. Float the tube between the rails and use a some blocking caps in/out. But would the noise performance at that voltage level be passable for pro audio line level?
Obviously this would be for a tube addition to general op amp circuits. Seems like a fun thing to play around with if noise can be low enough.
