[Hallicrafters] 3-Wire Plug...Uh, sorry to upset some of you.

[Rodger]

I have a few AC/DC receivers here and the ones that get a fair amount of 
use are on isolation transformers.  One that I like is this one from 
Fair:  http://www.fairradio.com/catalog.php?mode=viewitem&item=1585 as 
it also provides a bit of voltage reduction.  The AC/DC receivers are 
more of a potential danger during service as opposed to use however do 
be careful with those units that rely upon insulators between the 
chassis and case as these may be missing or damaged by the time you 
acquire one.
