Pat,
I do not believe they are interchangeable. Contact supp...@elecraft.com
and they can provide some test points to help analyze the problem.

I have a problem on my K3S. Suddenly in SSB the radio started producing
splatters. It is very evident when comparing with a K3. Trying with spectrum
analyzer in CW the wave is perfect, the phase noise also ok. The problem
persists excluding the KPA3A. The ALC control seems to be ok. It's likely a
failure in the KLPA3A driver card. For troubleshooting can i insert the LPA
card of the K3 in the K3S ? Are this cards interchangeable ? Thanks
