I know these threads get done to death, and become a grab bag of suggestions only tangentially related to the subject matter ("Buy a used Adcom GTP-500II instead!" "Psvane makes the best new-production tubes and I'll CUT anybody that says different!") but that's okay, right?
I'll be building a stereo tube preamplifier soon. This will be my first scratch build, to be done concurrently with a SEP EL84 stereo amp.
Objectives:
1) Be able to drive a wide variety of amplifiers
2) Be relatively simple and inexpensive to build
3) Be compatible with 280V-0-280V power transformer secondaries (I have a nice NOS transformer)
4) 9-pin miniature tubes from the 12A*7 family strongly preferred (I have lots)
Suggestions, anyone?
