B&O 500ASP ICEpower modules. Six available. 500W RMS into 4ohms. Has integrated switching power supply that operates on either 115V or 230V AC. Also has DC rails to drive external amplifier modules.
These unit are damaged. They all have some operational problem. No audio output, won't power up, stuck in protection mode, etc. I CAN NOT tell you what is wrong with each module. None of the modules blow the fuse when AC power is applied. None of the modules have obvious major damage such as burned PCB traces, exploded ICs, etc.
Schematics ARE NOT available from B&O or anyone else for the modules. Someone experienced in audio amplifier or switching power supply repair can probably fix them. The harnesses visible in the photos ARE NOT included.
More information on this unit including application notes is available here:

These units are now on eBay. Here is the link:

I also have six of the 500A Mk2 modules. Same deal as the 500ASP modules. All of the 500A modules are broken in some way. These are the OEM versions that do not have the top heat sink for cosmetics. If interested, contact me at jhidley at comcast dot net.
