[TenTec] Modifying Centaur air intake to reduce air noise?

[Gary Tuck]

I took a pair of pliers and carefully bent each louver so that it was  
horizontal thinking that it might reduce some of the air turbulence  
and noise.  That did reduce the howl but it is still very noisy.  I  
was going to follow Carl's approach but actually use the amp so  
seldom that a pair of noise reducing headphones has worked just  
fine.  Turn on Centaur, flip switch on headphones.  Down the road I,  
too, am going to put in a voltage dropping resistor.  At one time  
Radioshack had a 50CFM 110v fan.  I don't know if it is still available.
