    Default Modifying MF Headphone amp

    Anyone have experience of modifying an MF V-Can headphone amp (version 1) and/or can offer advice?
    Currently it has too much gain and I can barely open the pot before it gets too loud.

    I will be googling it to see if there's anything out there but just wondered if anyone had already done such...

    I'm sure something could be done to reduce the gain.
    A schematic would help a lot but otherwise a little tracing of the feedback components.

    Not had much luck with Google re schematics (or anything much at all for V-Can) but will keep poking around tomorrow ....
