  • Behringer HA903 - Headphones amp - Repair

    Just to let you know that I got this old phones amp and it was not geting sound on the LEFT side out.

    After replacing various electronic components Cap and Resistor I figured that could be the OpAmp.

    The opamp are BE027 and BE037 so Ive search the web and found this great site with equivalencies Behringer Parts List

    I've replaved the BE037 with the LM348 and worked just fine.
    Didnt replace the other opamp BE027 = MC4558 (cause the problem was the other one)

    I been around this problem for two days, just let this notes here to help anyone :-)
