Ah, I seem to remember that the primary on my Sansui 8080db receiver was the
first winding. Sure didn't care for having to rewind the darn thing, damn
idiot they moved into my room in the barracks saw a stereo that was
unplugged and just had to plug it in. Power transistors were out due to
failure and the leads to them were loose. D*ckhead managed to fry the
transformer.

Not sure where the First Sergeant transferred this jerk to, hope it sucked.
