In Reply to: Have/would never use such a low gM tube in that role... posted by Allen Wright on April 7, 2007 at 12:18:02:
Yes, I see, indeed the 6SN7 has a gm of only about 2600 umho (on a good day).Allen, in your opinion, would a MOSFET source follower, with its high gm, be as good as or better than a tube cathode follower for driving an OP tube? I want to try a direct-coupled cf or sf driver, to avoid blocking distortion and, possibly, to get a little more headroom for transients by letting the OP tube go into AB2 (but not to operate in AB2 continuously).
