In Reply to: RE: I tossed the 6SN7s in my Preamp posted by Cory M. on August 18, 2009 at 20:21:56:
The Chenin preamp has TONS of gain, with the two sections of the 6SN7 directly coupled, so going from a dual triode to a single triode actually worked in my favor. I used only one to replace each 6SN7, so the heater current was identical to 1/2 of a 6SN7 (0.3A). I did fabricate an adapter for them, so the only wiring change needed was to move the output wires from K2/A2 to K1/A1.Pictures above of the adapters and the installed 2C22 tubes.
Edit: By the way, I like the change so much I'm currently in the process of rewiring the sockets so that I don't need the adapters any more. I'm also putting in Duelund output caps, TX2575 resistors, solid core silver wire for the signal path, etc.
