For folks that have ran into warped dial discs I found a solution, for mine anyway.? I had a Heathkit VF-1 with a very warped disc.? I took it out and applying heat to it and then placing between a couple 1/2" aluminum plates.? After several "lather, rinse, repeat, cycles, I had a flat disc!? This is very important when the tuning knob acts against the disc...
