I have heard about using the sst on the pins. Just be careful to put it only where you want it, it is very conductive.

I was skeptical, but they do work and Steve is a great person to deal with. YOu can trust his recommendation.
I think the new issue JJ Tesla is a very good tube. Also the new Tung Sol and Sovtek LPS. None are more than $20 and probably less. Just get them selected for low noise. I don't think it is necessary to pay for matching with the 834P, but I could be wrong here. IME it really doesn't pay to spend big dollars on rare NOS tubes unless you have really deep pockets or some special vintage equipment.
