...the 12AU7 is certainly the place to find it! I think back on how many times I glossed over your (as well as Eli Duttman's, among others) posts about the non-linearity of the 12AU7.
Meanwhile I was trying different coupling caps, improvements to the power supply, even different resistor types to try and coax some music out of my ST-70 with a 12AU7 circuit.
Then one day, after reading one of your posts about the clear superiority of the 6CG7 for who knows how many times, I finally paid attention. But rather than cutting board traces, and since I already had a few 6SN7s, I bought an 12Au7 socket to 6SN7 tube adapter to try in the circuit's voltage position. After so many previous disappointments I wasn't expecting much, but couldn't quite get over the level of improvement. I could finally listen to this amp for musical pleasure.
When I think of how much time, money and frustration I wasted, when the problem was the 12AU7 in the gain position all along. Ugh! What an awful tube to use for amplification.
