    Lightbulb MV1F without HA13001 audio amp chip. Is there alternative way to get audio?

    Hi all,

    This is my first MVS project and I bought a MV1F board that has the chip HA13001 removed.

    Now I am thinking how I could get audio again using for example headphones ouput or speakers output without install a new HA13001, is this possible? Would I need a external audio amp homemade?

    Any idea or suggest is appreciated.

    Regards

    Just tap the line level inputs to that chip. Feed them to a headphone amplifier or a speaker amplifier if you're using a cab. Pretty straightforward project, you can find the schematic for that chip with a quick internet search.

    Edit: pins 3 and 4 are what you want to tap from. Pin one is ground.
