My question concerns the 2N4101 PRX TO-66 transistors in which 3 have been blown open. . The part number and package appear correct other than being a different brand, I believe this should work.. And below if your curious about my findings so far. Below is additional information if your interested
Here is my findings so far from a misaligned power connector from the rectifier board to the regulator board, causing the regulator board to stop working and smoke smoke to come out.
here is the suspect transistors I found so far are as noted on the schematics I studied for A17 which you can see in the attachment
U10 1884-0065 PRX (Located just right of connector J2)
U7?? 2N4101 PRX (Located directly above C15)
U13 2N4101 PRX (Located just right of U7)
U4?? 2N4101 PRX (Located beside C15)
I checked other various transistors in circuit with a multimeter diode test feature for shorts or if open in circuit, they appear to be fine.
