I was having the same issue but haven’t been able to replicate it, but for what it’s worth here’s the measurements I’m getting in a operational state.

I’m having the same issue with my 4004 before and after cleaning and regreasing, though it’s sporadic. Given the electrical profile (should be 30v jolt then immediately diminished), I’d suspect a capacitor issue. Next time it does it I’ll try to scope it. And I’ll need to consider the schematic.
