I never seem to get to the bottom of whether it's the coil itself or the former becoming lossy.
That was my conclusion as well. I used to have a 501 and spent ages trying to improve the alignment. I even tried putting the coils in a warm oven for several hours and also trying the trick of passing a small current through them to warm up the windings and drive moisture out (similar to drying out TV line transformers). It only made a marginal improvement and I managed to peak the aerial coil....just. I decided it was probably the former and passed the set on.
