  • Re: What Are You Working On Now

    So today I replaced the transformer rubber bushings in my Beocenter 9500. It was a little awkward to lift the transformer in order to put new bushings underneath, but otherwise quite a simple task.

  • Beolab Penta mains hum / buzz noise

    Hi all, Further to my project of upgrading my Beolab Penta IIs, I have completed all the cross-overs, and re-foams. The results are great. I used to think the Penta design had limitations in the tweeter with poor high frequency response but now with the mods I am very happy. One issue remains which was...
