About 3 months ago, my servotronic started to fail: intermittent shutoffs and then I was stuck with minimum assist until yesterday.

Reflowing the solder, as was expected, didn't do any good, so I decided to work on the circuit itself. Sure enough, after desoldering the two transistors, Emitter-Collector link in both of them either had a ~5MOhm resistance or even was positive on the diode test. In other words, both were BLOWN, BURNED, BUSTED!

I've managed to get the P/N from them and ordered replacements from digi-key.com. Soldered them in and VOILA! :))
