P.S. The rig is a Kenwood TS-590s.

OK, after Tim, M0AFJ, informed me that the amp needed to have fuses,
and I dutifully installed same, everything seemed fine for a little
while. Thanks, Tim, for the heads up. At that point I tried it on
several different bands into a dummy load and into the ether and was
getting 500 watts out. Then, I decided to put a watt meter inline to
get a more accurate assessment of wattage and instead I got really low
output readings on several transmissions and then zero. I then took
the watt meter out of line and now I have the following phenomenon:
1. In bypass mode I get out full wattage -- 45 watts from rig, but the
KPA500 says it's 35. The rig's SWR meter registers very low SWR. A
KAT500 is doing the antenna tuning after RF passes through the
KPA500. 2. If I take the KPA500 out of bypass into operating mode,
output drops to zero, SWR goes sky high, and KAT500 can't tune it.
Seems it must be a short of some time that's somewhere in the amp
circuit and not in the bypass path. Any idea where to start to
trouble shooting this? The strange thing is the KPA500 worked FB for
the first ten minutes of its life.
Tnxs for any suggestions.
73,
Carl
