Jim, just to clarify, I put in the bi-polar replacement finals. We have 
some left for repairs.
They are not interchangeable with the MOSFETs.
We had to design a whole new amp around the new MOSFETs, the KPA3"A" vs 
KPA3.

You can set config menu "PA TEMP" to a higher number to have the fans 
come on sooner.
(this won't help if the fans go to full speed and you still don't have 
enough airflow).
