[Elecraft] K2 in Overdrive Mode: 20 watts ?

[JimWMiller@aol.com]

It is my understanding that the K2 is capable of about 20 watts output on the lower bands if the power supply is run at 15 volts and the high voltage output protection 
circuit is defeated.

Is anyone getting 20+ watts in this "over-drive" mode? 

I realized that this is pushing the rig to the max but I enjoy "life in the fast lane". 

If you're getting the 20 watts please share your experience. 
- What power supply are you using and how much current does it pull? 
- How hot does the final and drive get during transmission?
- Any problems?
