    Well I found the mod in the workshop so I have done it and it works

    thats all I can tell you and I'm over the moon with it. Theres sounds now coming from

    my speakers that I never heard before.

    If there's anyone in the Herts area PM me and you can listen and examine my amp at my

    house and report back I'm giving you an open invitation

    Regards Henry

    Won't you face a serious risk of self-oscillation in the amplifier if you remove the feedback caps ?
    It's quite common to see unstable DC-coupled amplifiers like this one go into self-oscillation at
    full power, typically at a high (inaudible) frequency, 100KHz or so, overrunning the amplifier without
    anyone knowing about it until it dies in smoke and flames.

    The caps were not present on the early versions but were introduced later on - for a reason.
    As I see it, they also add an amount of soft-clipping which will help protect your tweeters in
    case of distortion.

    I have given your question some thought there is saftey measure built in

    that would prevent the amp from serious over heating and just cut out.

    Hi

    I have taken my BM 5500 apart to do the mod and it does not have the

    four 220nf caps on it. The model is 2332 it also has a beolink sticker

    on the back.

    Regards Henry
