RE: Opinions please: need recommendations for a Triode driver for a 2a3

You seem to have a preamp that puts out 15v. That means that all you need is a low mu driver stage, and the 6c6 ain't it. My suggestions; 12B4, 6AH4, 6CK4, in place of the 6c6. They all have low Rp and a mu <10 and indirectly heated, which makes implementation easy. They are also inexpensive and somewhat common. The latter 2 use 8 pin sockets and the 12b4 uses a nine pin socket.
