Problem solved, thanks principally to Don Wilhelm. For those who offered advice on the evening of the failure, and others who later submitted hypotheses about the cause of the problem, my thanks again; and here's the diagnosis from Don:
". . . one of [the PA transistors] had a collector-to-base short . . . A bit of wire (suspected to be a component lead cutoff) was found on the bottom of the board. It is only speculation, but that wire could [also] have caused the initial short." A lesson there. Clean up before closing up. I ought also to mention that Don had the rig repaired, calibrated and aligned, and on its way back to me within less than a week of the day I sent it to him. Outstanding. So, stand back everyone: Next week K2 S/N 7637 will be on the air!
