Bingo. Into my Cantenna no problem all the way up to 1500W. I also
noticed during the antenna tests that my amp heated up very rapidly to
levels not seen before (over 70C). I had expected lower efficiency on
160, so I'll need to watch it. I was temporarily driving my Carolina
Windom, and of course it's not intended for use on 160. My 160M
inverted-L, with a nice low SWR, is not yet hooked up, pending the last
lawn-mowing of the fall on Monday.

What are you using for an antenna? Does the same thing happen if you
transmit into a dummy load?

I have just tried my K-3/KPA-1500 combo on 160. I find that I can
only increase the drive to 26 watts, to deliver about 880 watts input
before the OVR light comes on. Is this to be expected? Don't see
anything in the manual about it.
