516.0. "Amp causes speakers to pop" by BAHTAT::HILTON (Beer...now there's a temporary solution) Wed Apr 05 1995 12:06

    My new (2nd hand) Linn Intek is causing random pops in the speakers. It
    may happen twice in an hour, and can really only be heard with the
    volume up loud.
    
    Last night I removed all the interconnects, and just had the amp
    plugged in, with the speaker cables in, and the pop still occurred.
    
    I assume that it's being caused by something to do with the mains power
    supply.
    
    Would a mains spike protector help, or what else can I do?
    
    
    Any help much appreciated,

516.1Not much help, butESBS01::WATSONAnd so, it begins....Wed Apr 05 1995 14:1312
    I'm not sure. As the 'pop' only occurs with the volume up loud the
    problem is affecting the pre-amp section (the power amp is fixed gain
    so any problems are the same volume independent of volume control
    setting). It sounds like mains but I wouldn't like to bet on it.
    
    I've tried mains spike protectors to help improve the sound and found
    that they didn't work. Give Linn a bell on the 0500 no I posted earlier
    they are keen to help in sorting problems even if the product is 2nd
    hand and have been known to re-emburse dealers who are asked to help
    out.

516.3British disease?PEKING::GERRYTFri Apr 07 1995 13:2310
    My two-pence worth...
    
    It's just this sort of thing that steers people to buy Japanese
    products!
    It happened to me with an old Armstrong Amplifier years ago...ever
    since then it's been Technics or Sony.
    
    Sorry Mr. Uk manufacturer

516.4Hopefully fixedWOTVAX::HILTONhttp://blyth.lzo.dec.comThu Mar 28 1996 12:007
    Fixed the pop in the Linn/Speaker, by getting 2 �2.50 suppressors from
    Maplins and fitting one in the fridge plug (which I don't thing
    worked) and one in the amp plug (which I think did the trick).
    
    It's not popped in 3 hours yet, so fingers crossed!
