[Amps] K3 Drive Levels and the SPE 1.3K-FA

[dgb]

I run a lot of rtty and digital with my K3. I always set the amp to the 
mid range getting 8-900w out. It takes only 8-11 w drive from the K3 to 
accomplish that.

Note: SPE recommends to run the amp in Mid Range for digital operation. 
When I first got the amp I made the mistake of running it in the high 
range and melted the copper heat sink, which was not considered a 
warranty repair, and was an expensive lesson learned.

Over the  course of the 3 yrs. that I've owned the amp,  I have blown 4 
LPA's in the K3 running it at 8-11w. With latest repair the tech 
informed me that the "LPA is not rated for continuous duty at upper 
power levels (like the digital Modes)" They suggested running 13w vs 11w 
so the LPA wouldn't be used. If I do that it over-drives the SPE in the 
mid-range.

What is my suggested recourse?
