And if you find a shorted SCR, carefully check the reactance transformer connections on the back side of the board or cracks in the board traces from mishandling. I remember we had one brand new out of the box that had a cracked sweep board.
Also, the sockets themselves could get iffy after many years and hours. Flush them thoroughly with a circuit board cleaner and re-pinch the pins with a sharp awl.
