Well I'm an intelligent person, I think. At least intelligent enough 
to read the manufacturers data sheet that says " in a horizontal 
position, the base pins No2 and No6 should be positioned vertically 
one above the other"

Then of course there's those beautifully constructed 813 amps in the 
1968 ARRL handbook 
http://www.arrl.org/files/file/protected/Group/Members/Technology/tis/info/pdf/68hb195.pdf. 
Yes the tubes are on their side, and that seems like a quite an 
intelligent article also.
