Hi. I'm trying to find a quiet squirrel cage blower to use in my homebrew 4-1000A amp. The one I'm using now takes abt 30 seconds to wind up to it's 3000 whinny noisey rpm speed. Anyone out there have a nice sized, quiet blower for sale or can put into a place to find a really nice unit? Any help much appreciated. Thanks, Ron K6ZL.
