On Sunday afternoon it was now time to figure out why the lights in two rooms were flickering. Also along with the lights my two Astron power supplies would let out a deep hum now and then as well. I began by turning off the circuit breaker to the upper rooms to see what all this circuit breaker fed. I then went to each outlet to see if there were any loose wires. I came across a box that had many neutrals tied together and another group of hots tied together. They seemed to have no evidence of burning or overheating and all seemed to be very tight with the wire nut holding each set together. I still gave both wire nuts a few good turns and put all the wires back into the box. I then went down again to turn on the circuit breaker and see if the problem was fix....low and behold the problem was gone and has never returned since. So even though the wires did not seem loose they must had been just enough to cause the lights to flicker. It's time to go back to radio fun!!!
