Good idea Don, once I get it fixed I will do that.

Most of us use the local audio for our speaker and the line audio is usually open. With the volume of the line audio up there is no load on that output transformer. To combat this, I put a 600 ohm resistor across the line output on the back of the radio. This gives the line audio a load and saves the transformer. (The resistor is actually 560 ohms 2W)
