i was wondering the same thing... i have the logitech z-560's with the blown amp. I opened up the amp and figured out that i could probably fix it, on of the onboard semiconductors is blown. The only thing is, logitech took the control pod, I was wondering if anyone could get ahold of one or if someone was willing, take theirs apart and make a schematic of it so i could custom build one. let me know if anyone runs into the control pods for sale. thanks
