[Amps] Alternative cooling strategies for SB-220?

[Dave White]

I'll second that as a good idea. Also you may wish to mount the blower on rubber bushes to stop the vibrations from using the amp chassis as a soundbox and putting sound-deadening lagging in short pieces of plastic drainpipe around the air entry and exit vents.

Or build something with a water cooled tube.  Or even a vapour phase cooled tube as per the 'Stanley Steamer' in the old Eimac bulletin.  The latter using the latent heat of evaporation is the most effective cooling method of the lot

Build an enclosure that vents out the back...  equipment built into  
the wall concept.  That will drop the noise at least by half.
