    Hello all,

    I am trying to resurrect an old Acoustic 270 (the guitar version of the 370) that is missing several components thanks to a previous "tech" and his butchery. I played through one many years ago and really liked the tone.

    The service information is available for the 370, but they are a little different.

    Any help appreciated,

    Techs and their butchery, if they knew what they were doing, a lot of gear wouldn’t be destroyed.

    There were several different versions of these amps, with a similar architecture. Sometimes studying the architectures in context with how they should work can be valuable. Often, for the circuit to work properly, the values will become apparent.
