No leave the drain resistor clipped on while the amp is powered down, the caps can refresh themselves and release the voltage, even if you think they have discharged.
Never forget, one hand measuring, - lead clipped to ground (or the other wire when measuring the AC heaters), other hand in back pocket. It is so easy to slip off a pin and get a short.
Obviously you need to disconnect the drain resistor before you pwere up.
To Hackworth 1: If you think that getting a 400-500v DC shock is a good lesson, then you shouldn't be touching HV parts. This is very bad advice, if you have a weak heart and the charge goes across the chest, say from one hand to the other, you will learn possibly your last lesson.
