Hi Paul, If the green AC light is on and the PS 50V LED is not coming on when you try to power up the amp from the RF deck front panel it indicates that the two boxes are not talking.
It sounds like the control cable between the amp and PS is not fully seated. Try unscrewing it on both ends and re inserting it firmly without depending on the screws to pull it in tightly. As an early field tester for the amp I suspect you may have one of the early pre-release control cables that had slightly long screws and may not seat fully if you relied on screwing it in to seat it. In any case, we can also get you a new cable to try after we are back in the office Tuesday. 73, Eric elecraft.com --- Sent from my iPhone 6S > On Feb 17, 2019, at 3:41 PM, paule408--- via Elecraft > <[email protected]> wrote: > > Last August, I had my KPA1500 repaired by Elecraft as one PA transistor > failed.
