[Elecraft] K2/100 power output

Hello My K2/100 just recently started going to 100 watts output as soon as I set the output to 11 watts or greater. I disconnected the amp, and am back to the qrp version and everything works fine. So I asume the problem is with the amp. Am I correct? Thanks Scott N5SM

Scott, Yes, the problem is with the KPA100. The most likely thing is that diodes D16 and D17 are damaged which results in the KPA100 not being able to tell the K2 that power output is being developed, so the K2 just increases the power to the max in an effort to obtain a power output
