     In terms of a typical amplifier - pick one that uses a pair of 
3-500z for example; any one - a TenTec Centurion, a Kenwood TL-922, 
an Ameritron AL-82, etc.  Would it make any difference in your 
maximum output power if you used #12 gauge or #6 gauge mains wire for 
the 35-foot run from the distribution panel to the plug in the wall 
for the amp?

     I am talking about a typical amplifier here, not one of those 
"export only" QRO or Command Technology 3-tube 5-KW things that no 
Ham uses :-) . . .

     I think that was the intent of the question by the original 
poster way back when.  Is the voltage drop on 35-feet for 12 gauge 
wire going to make any difference on the output of a legal limit amp?
