Harry: Let me speculate. When the KPA100 is "next to" the K2, you
have it everything on your bench and away from the power supply. But
when you have the KPA100 "in the K2", you have returned everything to
the operating position, which is near the power supply. Obviously, I
could be very wrong in my speculation, but it sure sounds to me like
you're too near a linear power supply or other source of AC magnetic
field once you try the K2 with the KPA100 in place. Try moving it
away from the problem source.

Hello,
I just finished the KPA100 without problems.
With the first test I hear that the sound of the modulation is not
good, it looks like a interference with a 50 Hz sound.
That is always, with 1 Watt output or 100 Watt output, it make's no
difference. My powersupply is good.
I check the alignment specialy the bias, that is good!
I was listning to the modulation with the KPA100 next to the K2 and
everything was normal.
Hear is the problem: With the KPA100 in the K2 the sound is bad!
What can I do? I check the cables, everything is normal.
