MC2301 amplifiers - Tube rolling 12AT7's
My friend Bob (vintage tube) made me an offer I could not refuse. From his personal tube locker stash of old stock tubes he has loaned me four each of the following 12AT7 tubes to audition in my MC2301 amplifiers, Siemens ECC801S, Telefunken ECC801S, and GEC A2900 (original Genalex 12AT7 made in Great Britain). All have been tested and matched, and are as new. This is a real thrill for me, especially since I would not likely purchase this many 12AT7's just to play with.
My MC2301's are using Gold Lion KT88 power tubes and Gold Lion 12AT7 voltage driver tubes, so I am comparing the Gold Lion 12AT7's against old stock Siemens, Telefunken and GEC.
I am in the early stages of my audition, having about five hours of listening in comparing the Gold Lions to each of the other manufacturers tubes, and there are some surprises. I have been taking notes, playing the same five songs over and over, swapping 12AT7's and listening intently. I am not finished with my critical listening, so I am not yet prepared to reveal any discoveries, but suffice it to say I am having a grand ol' time enjoying this opportunity to roll some fresh bottles through the 2301's. More to come.
See post #20 for full review.
