> This method is also useful for restoring the mid-30s AC-DC sets with
resistive 3 wire line cords,the kind that set your curtains on fire. You
don't want to use a resistor in the cabinet due to space and heat
problems; a capacitor is just right...or certain sizes of fluorescent
ballasts, just used as chokes.  ........

The problem I have with series impedance voltage reduction is the 
deterioration of voltage regulation.  For an AA5 current is pretty constant 
due to the consumption of the 50L6, 50C5, etc. output tube.  Likewise for 
receivers in general.  Anything with substantially varying consumption 
should be transformer supplied, IMMHO.
