I have recently aquired a very clean pair of Penta II speakers which I rebuilt with 8 new midrange drivers from B&O. They are mated to my beloved (and restored) Beocenter 9500.
The Pentas have a turn on "Pop" when the system is powered on. It's not bad, but I swear I read someplace that there was a fix for this.
Does anyone recall the article? It involved a few diodes to trickle charge the main capacitors in the amps in order to avoid that pop.
But I can't find it again.
Anyone?
