"How much gain do you get from your phono stage?"
I haven't measured it. All I can do is repeat what I said in my post.
My cartridge is .2mv output and I use a Jensen 1:36 transformer so I'm putting 7.2mv (or so) into the phono pre. The output is stronger than my CD player.
You would have 6mv. I think you would have plenty of gain. You run a line stage preamp with gain, right? I don't have any gain in my AVC.
"I need at least 40-dB gain with 100k-ohms input impedance. "
In a tube circuit the input impedance is simply the value of the first stage grid resistor. I left that resistor unlabeled in the schematic as it can be any value it needs to be for cartridge loaded.
