hello forum, my last project thing of hooking up headphones to any pwer/integrated amp using a 'flexible box' with swappable resistors is coming along nicely, and i was looking at mains power filters on ebay and they seem rather expensive, and so ripe for DIY!

anyone have previous experience with these or know of resources on making your own? cheers!

Plenty of other threads around about this, so search around, also search the net for DIY audio mains filter and combinations of those words!

Wouldn't it be cheaper and better to just build a better power supply for your amp than to mess around trying to clean up the input AC going into the power supply?

Try an isolation transformer and a EMI/RFI filter. Maybe $25-$30 for both if youmlook around.

Anything else means your amp's power supply isn't good enough.
