[Amps] plexiglas isolation in coils

[Tom W8JI]

Are you sure the early production - the one I had - used 
#10?>

Absolutely. From number 001.

Perhaps
it was changed to #10 in later production based on (bad) 
experience?>

Not a chance. Never was number 12.

The only coil mod ever made was moving the 40 meter tap off 
the 160-80 coil and on to a #8 guage winding. So the size of 
the 40M coil went from #10 to #8. Probably happened around 
S/N 100 because of feedback from a KW output BBS user. So I 
did change components based on customer feedback. The blower 
downsize was a result of customer complaints.
