That was my point, although I may not have been clear. There is no

That's just not how ADF circuits typically work. I think you're
making all this up. Otherwise, you'd understand how the "oscillators"
work when they're commonly digital PLL's, and that if a receiver did
alignment, it sure ain't gonna be due to "drifting tantalum caps," as
if they are especially prone to do that in the first place.
