Power Supply Help
yes
And I removed the PNP transistor and it seems to be ok. I got the expected diode voltage drops (about .6v) on the correct pins
pin side of transistor circled in red. only thing that looks iffy at all
My guess is this pot (only one on the board) can adjust the output voltage
B948 -> Silicon PNP Power Transistor 2SB948 datasheet(1/5 Pages) SAVANTIC
Found the positive output lead was loose
3904 -> a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications
only IC on the board
C358C -> LOW Power DUAL Operational Amplifiers
even the CAP looks good, no bulging etc
