[Amps] Cooling (GS35B)

[Tony King - W4ZT]

Robert,

I've also noticed that blowing air from the end will not provide enough
air to the tube on the opposite end. It's the old "hole in the hose"
problem. The air is best blown in at the mid point between the tubes
either from the bottom or the long side.
