Sounds like one of the output transistors went bad (probably open). This would give you half power and higher input (IC821 to amp) swr.

Hi, my 70 cms amp has suddenly gone low power (50-60w) and the input swr appears high. where can I get a copy of the circuit do do some fault finding and is this a common problem as my IC821 with a 3 ele yagi does not have sufficient power to get me onto VO-52, Regards Mike G3LGR _______________________________________________ Sent via [email protected].
