I won't quote any text from it, out of respect for his copyright statement.

I've read that Aiken article before David, it says more or less the same as most other articles I've read, given the impedances involved I would have thought it wouldn't make too much difference which way round the capacitor is connected in your average radio as a good chunk of any hum voltage on the outer plate is going to make it to the inner plate, as that's what capacitors do,
