You are just going to have to trust us on this until you see measurements for
yourself. The Heath designers did not just get up one morning, place a fan
from the parts room in front of a pair of 3-500Z's and start shipping kits. Rich
and others have explained the brilliant engineering scheme in the SB series
amplifiers...I will not repeat it.
Suffice to say that the entire tube envelope gets cooled with this method.
There are no "hot spots" or "eddy voids" to worry about. I don't use the
blowing out of the candle example. I like the example that I prove every
time I dry my hair...place the dryer so it aims directly on your Adam's apple.
The hair on the back of your neck will dry just as fast as if you had gone
into contortions and aimed the dryer directly on the hair.
