I am glad the MC75 voiced more dynamic and cooler sound signature than MC275 in stock form, which give me opportunities to use old stock tubes that often have more attractive timbre than new production tubes. Now, I am using Holland made Miniwatt 12AX7 "fat boy" in V1, I called then fat boys because they are fatter than any other 12AX7s I have. Mullard CV455 in V2 position, and E180CC Philips Miniwatt Holland made long plate in V3. I don't recall which one, one of the small stock tubes have imaging problem I mentioned in earlier posts. I disagree with some people here saying Mac voice their amps based on the stock tubes without testing NOS options. I have never tied Telefunken in any of those positions, well, I should try but my wallet says nay. What do you guys think?
