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.
