Of course he did: he also "wisecracked". So? 
Gee....Lighten up.

It seems to me that an amp that is working exactly as it should doesn't need 
mods. As Clif wisecracked: "If'n it ain't broke, don't fix it."

I think you mean "parasitics". A decent amp better NOT have any VHF 
harmonics!

Huh? What voltage drop? Filament voltage? Filaments should be run at 3% 
low, anyway.

If'n you don't watch the Red Green show, you are missing one of the finest 
spoofs in the Northern Hemisphere. :-)
I will take this occasion to post my personal view of most "mods": they aren't 
worth the effort in 99% of cases. 
The engineers who designed the equipment were, for the most part, no 
dummies, and did almost everything they did for very good reasons.
Most ham mods I have run across usually make the subject equipment work 
WORSE than it did without them.
SOME very few, very carefully thought-out mods are worthwhile: like 
Measures' QSK mod (he calls it the HSS mod) for the various amps. That is 
excellent and works like a champ...when properly installed.
