[ARC5] BC-221

[WA5CAB at cs.com]

I reread your message.  What I described might be what you mean by 
cosmetic.  I've never taken the time to draw out a schematic but it has three tubes, 
like all of the LM's and 221's.  So I'd guess that the differences between 
it and the first production models are mostly mechanical.
