Hi Dave:
You wrote, regarding the KPA100 cooling fan...
I note it blows air INTO the KPA, but there doesn't appear to be
much by way of provision for the warmed air to get out, so I guess
oscillators are going to move around quite a bit when the warm air
circulates around and around.
The 'cooling' air exits out the top of the KPA100 assembly, at the
front of the heatsink fins AND out the bottom of the K2 case. Pretty
LOW VOLUME.
Maybe a nice, quiet ex-computer muffin fan sitting on top of the
heatsink might be a better way of cooling the PA?
I've made a cooling 'plenum' for my K2, using a very lo-profile cover
and a tiny muffin fan from a CPU cooler. It pulls cool air in from
outside across most of the heatsink fins and exhausts straight up. I
can supply illustrations and some info on the design if you, or
anyone else might be interested.
Cheers,
Tom N0SS
