Greetings Ian
Besides the lower back pressure advantage of blowing into the anode
compartment, this method also cools the tank components. This helps reduce
thermal tuning drift in very hi-Q tanks.
If the heating of the passive tuning components is a problem with an
amplifier that has a pressurized sub-chassis a hole or holes could be
provided by the designer, this may be a practice with some HAM products.
I have seen it in some commercial products.
