ok this is how it went,sold a guy my x80 base box and when i got it back it did half the watts so im looking for pics of the inside at the variable dial how it is wired thanks
Half the normal output in most cases = Blown final transistor my friend.
bypass it and see what it does...
Those XF amps, don't like the swr been above a 1.3, with the amp on.....and they don't like too much drive from a radio, .....been there, done that..
I have an X-80, and my lying technician told me they didn't hold up well when working sideband.
