[Amps] Getting rid of blower noise

[Robert B. Bonner]

Why not build a 100% active canceling room?  Have it so even your voice is
cancelled out then start from there.

The nice thing about this design is that the microphone is apparently
only needed to get things started. Once you have everything set up for
dead silence the microphone is not picking anything up so I guess you
could unplug it and move the tripod out of the way.

*** Seriously (yeah right), you need a condenser microphone on a tripod
3
feet from the affront of your amp.  A mic amplifier, a phase shifting
network, an audio power amplifier and speakers all bolted into the amp
rack
next to the RF power amp...  

When at full power adjust the phase shifting network until the amp is
silent.  Total BOSE system for your amp.  It would probably neutralize
choke
talk and everything.  Dead silence.
