Boston Accoustics Micro90pv subwoofer circuit diagram. This is reverse-engineered diagram - incomplete - as an attempt to faultfind my silent sub. No guarantees - actually I guarantee this is not correct. Manged to get the sub working again, though.


Reverse-engineered circuit diagram of the Boston Accoustics Micro90pv pre-amplifier board. Including voltage sources for simulations. When simulating this, it seems the gain in this preamp is very low. Uncertain if everything is correct around the signal path of the second op-amp
