[Elecraft] KX2 Starts Off with Low Output on 10M

Hello!  I recently purchased a KX2 (#757) from a friendly member of this list. 

I have a local 10m meetup I attend frequently, and I noticed a strange behavior that I'm now able to replicate.  When I first switch to 10m, I have extremely low output power (one bar on the RF meter), even when set to 10w.  I have to keep transmitting for 30-60 seconds, and if I do, the output power starts to work its way up to the full 10w.  As you talk, you'll see 2 bars, 3, then 5, etc eventually to the full 10w.  If I switch back to another band and back immediately, it will display the same behavior (start on one bar and then climb slowly), but if I stay on 10m it will continue at full output for the QSO.  I isolated this problem this morning and can now replicate at will.  It's not just a display issue, my local meetup actually noticed it in audio (I start off in the noise, and come out to normal over time).   

I mailed Elecraft, and they suggested it was a hardware failure in the final stage. Before I return the radio for service, has anyone experienced this issue previously and found it to be a configuration issue that didn’t need hardware repair?

Thank you in advance!  Other than this issue, I absolutely love the KX2. It took me 3 small HF rigs to land on it, but it suits my needs perfectly.
