[ARC5] ARC5 receiver capacitors

[Sandy Blaize]

I would stay away from the "stock" 'can caps' they used in the SCR-274N 
sets.  Use a small 1 or 2 lug terminal strip and some very small mylar 
.047 caps at 400 volts.  They are cheap and will last a long time.  A 
flat disc ceramic cap would also work fine too.  Yes those are mostly by 
pass caps as I remember.  Haven't rebuilt one of those in many, many years.

Had nothing but ARC5/SCR-274N stuff for years when I was in high school!
