Quoted from Mando:Went ahead and got the new coil, seems stern may have upgraded them over the years.

Also grabbed some of what I think are the correct replacement transistors.
TIP 120(they didn't have 122 but says this replaces them)
I will probably let the pro repair it this time, but I will watch and practice my soldering in case there is a next time Wont hurt to have these on hand.
I do not think TIP102 is correct. They should be FET based IRN transistors.
