There's no replaceable fuse on the 200ASC. It uses an electronic fuse on the PCB which you shouldn't change.

I'am sure that PS audio made some modifications to 200ASC, and it's 110V gear now.
If you have photos of 220V version (2 sides ) in hi-res - that will be helpfull.

thx for your help


this and a trio a100 right? I need the drawing board input signal, would be grateful

They sound as good as my junk test speakers will allow them sound. And no, the highs are not missing or rolled-off like some have suggested.

They may only be ~40W amplifiers, but that is perfectly fine with my neighbors. If I played them even close to clipping I would probably have someone banging on my front door.

I replaced the 50v 560uF supply cap with a Panasonic FC 63v 820uF. I also added two additional 63v 820uF caps across the J2 PS header.

Adding too much capacitance to the power supply will make it break from the inrush current.
