I should point out that I have done a full reset (power up plus band up and band down). The radio is powered by a 50 amp 13.8 volt power supply - I am aware that the rig is sensitive to voltage changes (I've used it on batteries) - This is a fault, but not the PA. I guess something like a relay stuck in the LPF or a capacitor has died?
The fact the radio will do 95 watts on 10 metres implies it's fine.
Any advice greatly received.
