That's part of the satisfaction.  I like to build things.  I want to build 
it in a custom housing that the Grundig will sit on top of and house a 
couple of speakers.  The radio has its own power supply, but its probably a 
switching style and I want a nice, "quiet" power supply.

I've decided to go with low-leakage aluminum electrolytics.  Cuts the cost 
waaaay down.

Thanks for all the input guys!
