I know a period or comma is needed somewhere but I can't figure out where.
"Before attending xxx I spent 6 years in the military where I worked as an avionics technician repairing and troubleshooting various avionics and instrumentation systems aboard military aircraft."

Agree that there should be a comma after "xxx." But I would consider restructuring the sentence as I feel the repetition of "military" and "avionics" (and the multiple conjunctions) makes the sentence more cumbersome than need be. In particular, I would suggest:
"Before attending xxx, I spent 6 years as an avionics technician in the military repairing and troubleshooting aircraft instrumentation systems."
The reason for the changes:
You already say you were working for the military -- not need to specify they are military aircraft.
You already say you were an avionics technician -- it is safe to assume at least some of the aircraft instrumentation you work on are avionics related. And (I could be wrong, as I am not in this field) it is an electronic system on an aircraft -- isn't that by definition avionics?
You originally said "I worked as." Maybe this is just my personal preference, but the verb "worked" is almost meaningless. You had a job repairing and troubleshooting. It is inherently work. No need to clutter the sentence with it.
You are completely right. Thank you so much! Very clear and precise.
