I love the SED 6L6's so much that I'm now interested to try their 12AX7's in my Mark IV. At the tubedepot.com they have a few options; high gain, low noise, balanced triodes etc.
My question is what option would work best in each tube position? Balanced triode in the phase inverter, low noise and microphonics in the input stage? What about high gain rated tubes? Are they worth the extra noise?
