Peter, In that case, I would suggest looking at the control board to see is there is something awry there causing a path to the AGC circuits below P4. Also you might check the VRFDET signal line on the KAT2 - hint, removing R6 should disconnect the VRFDET signal line but leave the cable connection present. Check the cable for internal shorts between the conductors with an ohmmeter - that might happen in storage if the cable was sharply bent and insulation creep occurred.
