Plenty of reports from four stations throughout the day at distances up to 376km (F5WK in JN18HP) then all stop at 1740z. Still radiating, about 40W into the antenna now. I've optimised the PA output by changing the transformer and added a few tap positions for loads from 50 to 150 ohms. If there's any interest in this rather standard linear PA, I'l write it up - if not, shan't bother. The FETs would have to be substituted anyway.
