I don't have it right now, but it was universal recommendation. The 6 ohm was just too much of a load and was cooking the regulators. That's a step I do to anything that comes through with a 6 ohm resistor. Note that on Legacy, they finally started bolting the triac to the frame to try to keep it from cooking. They don't cook as often, but the Legacy ones still fail.
