    Hi! I did something really dumb when attempting to test a circuit. I plugged in an AC power source instead of a DC.

    Some caps blew... I'm not sure what else might have broken. Can you guys help me figure out what probably broke by listing the components?

    The system is designed for 12v-42DC and I used 24VAC

    • 680uF 50V capacitors- One out of 3 blew. Could the rest also be damaged?
    • 100Uf 16V capacitors
    • 10uF 50V capacitors
    • LM317
    • LM317HV
    • BS250P Mosfet
    • 10K Resistor Network
    • 7824A JRC MA009A (I believe its a voltage regulator as well)

    The rest of the components are not polarized.
    Should all of these components be dead?

    hi there
    welcome to the forums :)

    any or all of them could be faulty, you would need to test each one individually to find out which ones still work the way they should

    ya wont do that again in a hurry will you ;)
