Possible PA failure?

in Power Genius XL Amplifier

I have PGXL SO2R, it's been working fb for several years. When I tried to use it today, the power output was low. It was only the power from the radio, so no amplification at all in the PA. Tried on 6m and immediately had a SWR warning.

Next step was to connect a dummy load directly at the A output. Exact same results. All self tests OK when I start up the amplifier. Anyone experienced something similar?

    If you look at the front panel, it will show the drain current (Ia I think it is). When you go from STDBY to OPER it should show about 4 Amps.

    If it doesn't show that, then you likely have a PA failure.

    Time to open a support ticket.
