Those "loops" as you refer to are actually inductors of a very small value. They are in all intent a passive component. The size and shape derives the inductance value. If you burned one out you were definately sinking some heavy current, check your output transistors as you prob cooked at least one. Check all bias resistors as well. Did you have the thing fused?

A small copper loop beside the power adjust pot. burned thru the board and took out a cap.I was able to get it back online but am worried about overheating . mobil units don`t have large heat sinks. What is the normal power setting? These small copper loops act as a jumper from one trace to another. What are the correct term for these loops? Dave 73
