@nickbloomfield4433 4 года назад

Hey mate, thanks for a great video, really helpful info and works great. One question though the 47k resistor on the neutral side gets extremely hot, is this normal? I’m using a BT137 (what I had on hand) and it doesn’t get warm at all? All cct’s I’ve seen like this use a BT136 with a heat sink. The fact this component doesn’t heat up at all in my cct makes me think there’s enough of a difference between 136 and 137 to cause issues. Anyone else experience a similar problem? Only difference in the cct is a 4N25 instead of MCT2e and the BT137.
