[Collins] Boat Anchor Fans

[Bob Sullivan]

Ray, et.al.,

I agree - paying for any kind of "fancy cooling system" is absurd. A simple 
muffin fan will do the trick nicely.
Forget  "power supplies" ... just use the 6.3vac already available (like 
KN4I suggests), rectify it using a simple bridge and capacitor and power an 
inexpensive 12vdc fan pulling air out. It makes an amazing difference in 
temperatures.
