My orange drops have a line on one side showing the outside foil...

IF I remember right, the outside foil bit was most useful when one side of 
the capacitor was grounded or attached to a much lower impedance node thus 
using the outside layer of foil for shielding to some extent. As far as 
reversing the orange drops, it should make no difference whatsoever since 
they are bipolar. Also, keep in mind that caps in series (with the circuit) 
roll off the lows and caps in parallel (to the circuit) roll off highs.

Great info guys.
I will just remove the cap and see what the audio responce is like first. 
There was a 'foil side' on the original paper cap so maybe reversing the 
orange drop leads will help if the audio highs are too much without the cap 
in line. Not sure why the hum appeared, may be unrelated.
And thanks for the justradios & hayseed supply sources - forgot all about 
them.

I've had very good luck with justradios.com on caps. I've ordered a lot from 
them over the past few years for my rx restorations. They do have a $20 
minumum however. 73 Brian / w5ami
