Thanks guys, although I won't have a chance to try the set with the speaker plugged in for a day or so, it does make total sense. I too figured something was loading down the circuit, never thought about the speaker. Well not out of the woods yet, but one step closer. By the way, only two resistors were harmed during the smoke shows and sure nothing else was damaged. Was real quick cutting the power at the first sign of smoke. I will report back.

Thanks, Don
