    Default EUVL's (XEN Audio) Super Linear Headphone amp born

    Hi I finally finished my N-th class A phone amp.

    Welcome (Pioneer) Super Linear Headphone Amp designed bu EUVL (from diyaudio.com).
    Partick has a number very good mainly headphone amps to his name.
    This one is based on an old idea from Pioneer.

    This was my first extensively SMD (surface mount devices) project. I have learned a lot, the next one will be easier.

    PS As you can see it still need a proper volume control knob!

    Wanted to add more pics, but it does not allow me anymore.
    Have I exceeded the max allowed size somewhere, it would not even do rescaled pictures anymore

    you do get limits so you may have yes. most folk tbh use a hosting site or tapatalk. i use tapatalk a lot, but from pc only you need a host site like flikr, imageshack etc.. there are still some free ones. ive used imageshack for many years..
