[Damn autocorrect - Just noticed that it said photocopier instead of photochopper]

Nice.

Is that photochopper the same one as in the 419A DC Null Voltmeter?

I've heard many people talk about having the 419A turned off will help cause the photochopper to fail (the recommendation is to store the meter turned on) - Did you do anything to resurrect it or was it just working?
