    DuKane Model IA385 Restore

    Starting on this little DuKane amp I got last summer. I began with the power cord which was roached. I thought it a good idea to go with a heavy grounded three prong plug.

    Restore vintage audio, but which one?

    If you were me, what would you do? Currently, my best-sounding piece is a Pioneer VSX-4500S that I bought new. Honestly (and surprisingly) it sounds quite good when playing vinyl, FM, CDs. Dead quiet. Nice soundstage. No known issues. Certainly not a looker, tho. HOWEVER, I have several vintage...
