But I see a lot of DMEs with vibration failure solder joints at the large coil driver transistor. It's very common failure so it's possible the DME simply failed because of age and vibration.

The MSD coil has about 10 - 15% more inductance than the stock 911 3.2 coil, which will result
in less peak current & thus less stress on the coil driver.
