It does not turn on whenever the power goes out or is removed from the socket, the voltages are correct, when tsound is a short between the bases of the u707 and u701 it starts working again and stops working again when removed from the socket. | Solder a 10k resistor between the housing of the u707 and u701, working since then. | IOT Consulting | |
