popping sounds......
« on: November 24, 2009, 10:31:44 PM »
I used to live in the 'Burgh a few years ago and got a sweet stereo while there.  It is a mid '90s era Pioneer receiver and 2 JBL L40 speakers.  It sounds awesome.

Here is the problem - one of the speakers has started making fuzzy popping sounds - every few minutes or once per hour.. whether or not anything is playing.. but not if the receiver is turned off.  I replaced the wire going to the offending speaker, no change.  I switched from the A to the B channels on the receiver - no change.  But when I switched the wires so the left channel goes through right speaker etc and the popping followed the wire - it was left and is now right.  Receiver, eh?  It has been moved a lot and lives cramped in a cabinet if that is relevant.  Doesn't seem to get too hot though..

Appreciate any help.  I am in New York City if you know any good shops here.

Thanks, Andy

Hi Andy,

Open up the receiver and search for bulging caps. Pops are cap related quite a bit.

Welcome to the forum.

If you cannot find a good place to take it, I would suggest a road trip back to the Burg on one of our Meeting nights.  Beer, Cigars, Music and playing with volt meters and a soldering iron. ;D

 Poping sounds can also be almost any component in the amp section (leaky transistor). Consider getting it fixed before it damages something else (speaker).
                                        just my two cents

 I had (Knock on wood) that problem with my SA-9100 but it seems to have went away. Are you a member of Audio Karma? There is a guy that can be summoned in the Pioneer forum by the name of Mark The Fixer, he knows everything Pioneer. Its really frightening how much this guy knows.
Pioneer SA-9100 TX-9100 SA 5200 CT F7272 HPM-100, KLH 5, 6, 17,  Marantz 1060, Technics 1100A, 1200m3d, Thorens TD111, Goldring GR1
