Hey folks,
Curious to know what options there are to substitue 6072a and 12au7 tubes in a mic preamp.
I have been reading that a 12bh7 should drop in for the 12au7. What characteristics might be expected? Is there anything to look out for in terms of pinout or wiring?
How about the 6072a?
Are there octal tubes that can suit?
What I'm looking for is better transient response. I think this is most critical for V1 (6072a), which tends to round off the transients at normal input levels.
Thoughts?
