I'm afraid I do not have much more information, my two 200ac modules quit about a year ago with a short shrieking noise and after that nothing. The 200asc refused to produce any sound after I took the pictures although the led indicates that it is OK.
I have no idea on what to measure or even what went wrong.

Damn, these modules are brittle, and it does not include a MCU system to give a hint for quick repair startup. Some generic test recommendations for SMPS/class D modules, in order:
- Check for mistakes in input wiring, I think I saw traces of wires being directly soldered to PCB connector pins one by one.
- Check standby supply (with module disabled).
- Check that signal supply rails and main power rail come on correctly upon module activation.
- Check that output stage is oscillating (carrier present at output). Check output offset. Check idle frequency.
- Check responsiveness to input signal. Follow signal through op-amp/IC chain if needed.

Hello gentlemen!

I bought a PS Audio Trio A-100-US power amplifier from the United States on iceasc 200asc modules. PS audio has buried something in the power of icepower boards and I have to use a transformer from 120 to 230V. Do you know what I need to change at the power input of ICEpower modules to power them directly from 230V? Please, help me if You can

Regards!

Really? The 200 asc is normally Universal Mains SMPS (85 VAC to 265VAC , 47Hz - 63Hz) That"s what the specs say...

Yes, I know, but PS Audio is something modifying and doing things for 120V for USA and Japan, and 230V for Europe When I connected 230V, I heard high-frequency squeak and turned off the differential switch at home. Fortunately, after connecting back under 230 / 120V amplifier worked ...
