    Guts look about like a 2k amp.. Pretty sketchy if it has a strapped RMS rating on the front of the amp

    Re: KARSTADT amplifiers?

    I guess I'll fill in the blanks...

    Its a Zenon board that's used in... iirc old sundown saz3000, atomic at3000, Rd 3250.. ect.

    Still have yet to put it to a test but will try in the next few weeks.

    Price was right though.
