[AMPS] SB-220 cooling

[n2bc@stny.rr.com]

Mike brings up an excellent point - "grabbing the wrong knob"

Our club has an SB-220. It's used by all manner of folks & in the frenzy of a 
contest it gets lots of abuse.   I found that changing the bandswitch knob to 
something significantly different (smaller) reduces the cuss words heard 
through the wee hours.

On the cooling thread....   We all operate using headphones - the noise 
from 'station #2" is always worse than any equipment noise.  This said, we have 
a big muffin fan (10" diameter - BIG!) sitting on top of the SB-220 pulling air 
out of the cabinet.  Makes a huge difference in the internal temps. We throttle 
the fan back with a normal lamp dimmer switch to abt half speed, the noise 
really not a problem.  

It's ugly, but then the '220 looks pretty stupid with that tiny bandswitch knob 
anyway!
