Re: HP 8662A Power up - overvoltage shutdown

Good chance you have an open electrolytic filter capacitor on the PSU motherboard.? From what I've seen, the supply tries valiantly to run in the presence of the resulting ripple, and it *almost* succeeds.? But the high peak-to-average ratio at the input causes the overvoltage sensor to trip. ? -- john, KE5FX ?
