Hi!
What is the opinion nowadays on using the original tone control by Baxandall, as published Wireless World 1952? Is it still worth incorporating in a diy hifi preamp, or are there better circuits? (Link below

He states in the article that it works best with a high gain tube like a pentode (EF86?). I would rather use 12AT7 and put a 5687 as a cathode follower after it. I tried simulating his circuit in ltspice but got questionable frequency response, not sure if it was my doing or the tube modeling that was lacking.
