Kevin,
Thanks for the through and informative response. I've currently have built a version with a transformer input so I think I'll give the cathode input a try. You make an excellent point about PP caps. After I posted this I did find one example of a 50's console that used a cathode input that used and electrolytic cap at the input. The author commented on this as being problematic.
You've raised an interesting question about why I'd want to use tubes as well. I have been thinking about as well especially since SS circuity could easily and cheaply do the job with great fidelity. In my case my goal is add character to the sound. While I'm concerned about adding noise I'm much less concerned about perfect fidelity. The digital recording interface I have has great fidelity but sounds cold to my ears. It's going to be an experiment!
