I would get some Deoxit and remove the KPA3 from the main board. Apply minimal amount of Deixit to the connector pins and insert/remove the Amp about 10 or 15 times. Wipe pins with lint free tissue and re-apply Deoxit (use toothpick) and insert the amp firmly and reassembled the radio.
Let us know what/when you solve this.
