I received a BR103 SCR that can be used at the place of the E10122 in the analog board of the Macintosh Plus (but the pinout is different). I found another resistor that was open circuit. I tried it and it welcomed me with the classic “bong” indicating that the logic board was correctly powered and the self test was a success. Yay! Now I have to investigate why the screen remains black.
