[Elecraft] KPA1500, 4 years old, Intermittent LOW GAIN error.

[Dave]

I had problems at one point due to the 3 watt resistor on the filter board desoldering itself causing the amp to have errors. The RF deck went back to Elecraft and Renee got it repaired. There were also a few hardware updates done while it was back for a visit in Watsonville. 

I don’t think that is related to your problem but you could take off the bottom cover and take a look if there is any obvious signs of trouble on the filter or PA board. 

Having the updates done to the RF deck made the amp 100% rock solid after that.
