Other than the heater voltage, is the 6cg7 a substitute for the 12au7? The amplification factor, voltages and plate resistances are just about the same and the tube curves are much more linear on the 6cg7. Is the 12AU7 more suited to small signal amplification, i.e. less microphonic?
Just putting the question out there for thought.

- in most usage where the dissipation is low 6CG7s should sound just like a 6SN7 - Timbo in Oz 15:53:06 10/16/15 (6)
