<< < (4/8) > >>

johansen:
I have a circuit board from a fairly recent and common 2 ton heat pump, has aluminum wire for the common mode emi chokes. In  hindsight, i have seen this before in inverter microwave ovens. The connections are soldered, and no reliability problems that i know of

No, it is because most of his stuff is excruciatingly slow. He has a tendency to take 10 minutes to say what could be said in 1 minute.
