Rolling Tubes in the Atma-Sphere C-30 amp

I imagine there must be at least a couple of people who have experience with rolling tubes in the C-30. Suggestions would be greatly appreciated regarding what tubes to use for the best possible sound and which positions they should occupy in the C-30.

ONE day and you're surprised?

I had a pair of M60s, and I've had other poweramps that use 6SN7GTs in their frontends. In my and MANY others' opinions, there in no overall-finer-sounding 'N7 than the Tung-Sol Roundplate. They seem to be worth around $100 now, with just-found NEW ones well over $200. (They stopped making them in the early 1950s, I believe.)

One other note--even those that test low in various tubetesters still sound great in poweramps.

E-mail Ralph at Atma-Sphere to ask about the most-audible tube positions.

Sabai, I have no idea how many TS-RPs others are using. I suppose some love to get 'full' benefit from the glorious sounds of them and don't care what it costs. I used them in the 2 voltage-gain positions of my '60s.
