George,
I will check the fan air flow direction tomorrow because I am uncertain.
If you have the label out and the wires on the correct holes, yours is
likely OK.
There are 2 philosophies about the fan

There are 2 philosophies about the fan direction. One is that you
should exhaust the heat and let the assembly draw cool air
Interesting. I built my K2/100 about 17 years ago and the fan has always
drawn air into the cabinet and exhausted over the heatsink. So, I rechecked
the manual and disassembled my rig to check for proper assembly. Fan label
is facing out and wires are soldered to the right pads(red=+, black=-).
Ken,
Did you set the bias properly? What is the current draw at 12 watts?
Did you properly balance and calibrate the wattmeter?
Are all the diodes oriented properly? Check against the parts layout
near the back of the manual.
Make certain the fan is mounted with the label out and that the

I recently added the KPA100 to my K2. The heat sink gets VERY hot at any power
level above 11 watts (that's when the amp kicks in). The fan
That is the KPA100 manual. Sorry for
possible misdirection.

I recently added the KPA100 to my K2. The heat sink gets VERY hot at any power
level above 11 watts (that's when the amp kicks in). The fan is running at high
speed and pulling air OUT of the box. Just wondering if this is normal.
