    I would agree, it could be a condition it was left in while testing at the factory.
    Reset!

    I just did a reset...  It did change things...Fan does not kick on as fast but that temp sure goes past 60 deg C pretty quickly.

     I'm also checking the AC power as I agree with John, it could be an issue...

    Tom are you running your PG-XL on 120vac?  If so, that's probably the issue.  To give you a point of reference, with 25 watts of drive (Tune mode) at 3.8mhz my Amp is putting out 805 watts, and legal limit occurs with 43 watts of drive.  (My line voltage going to my Amp is 248vac, and tests done into a dummy load.  Output power measured on a LP-700 Digital Station Monitor.)

    Oops, I didn't look close enough at your video and missed the indicated 116vac.  Let us know how it works with a 220vac line.
