I believe that my 1954 REL Precedent tuner, which is a complex design using 15 tubes, has never been re-aligned. It works beautifully, and I cannot imagine it ever having worked any better (aside from occasionally when an intermittent problem abruptly appears, which is obviously unrelated to alignment).
During the 1990's I also had numerous Scott and Fisher tuners from around 1960 or so, and a McIntosh MR71 and two Marantz 10B's from the 60's, most of which also worked well without any realignment.
