> My KPA1500 (s/n 121) has developed a problem: 
> When applying power (15-20W) from the K3 to the amp, it immediately faults to:low gain fault ratio 3 (sometimes ratio 2 to ratio 6). The SWR indicator shows high SWR as the amp faults. 100w only from exciter will cause ATU to tune to 1:1 but when amp is switched on, it immediately faults as above. Looked through archives and manual. No mention of this particular fault. Any ideas would be appreciated.
