In Reply to: This might be a dumb question but that's my specialty posted by Permanent Waves on January 19, 2017 at 14:14:59:
Tube life is not measured in terms of signal output. I've never noticed reduced output over time with the many tube preamps and power amps I've used over the past forty odd years.
Just for grins, I ran 12AU7s 24/7 in a Manley DAC for well over a year and quite frankly, didn't notice much difference!
As you observed, the 5751 is a low gain version of the 12AX7 - all of the time!
