Video Teardown and Repair of an Agilent E4421A Signal Generator [TheSignalPath]

<< < (3/3)

KedasProbe:
What about a current spike due to hot plug-in of a board?
Or an static charge that somehow got on the board before plug-in?

Just thinking of possible ways to beak it.

edit:
If the collector of one of the two transistors would have become disconnected then I assume that would fit the behaviour. (should be easy to check by measuring the base collector current ratio)
