It plays records excellent without problems, however.... it has this buzzing coming from the speakers that can't be ignored when on medium/high volumes.

    JBL LX 66 Woofer Repair

    I recently was given a pair of JBL LX 66 floor standing speakers. The woofers needed refoaming, and I did that. Then I tested them. One of the four woofers has a buzz. How should I proceed? I've rotated the speaker 180 degrees in the cabinet with no results.

    Feeling a little buzzed :/

    Well, the receiver not me so much :) 2230 restored. Everything works great with a small itty bitty exception. The phono setting will give what sounds like a 60 cycle hum if the volume is up about 1/2 way. If I touch the chassis, it goes away. This started because in the loft where I had it, I...
