Any Home Made Line Conditioners?

[Structo]

Just wonder if anybody has made there own.
They don't seem like much more than caps and MOV's on some of the ones I've seen.

I'd been thinking about that. I would want to add some power filtering with maybe some big AC caps and some EMI/RFI filtering. Throw it all in a big box and plug it in.

I've often thought to try a modular line filter.... but havent yet
seem like they would make for a really cramped chassis...
maybe on the fil. voltage ... its the least regulated

Here's some ideas:

Any of you guys with scopes ever anylize the house current to see what kind of EMI is on the line and what is generated by various items in your household?

I haven't been able to try that, but If I have an amp plugged into the wall, I can tell when my fridge/computer/dishwasher is on and also my neighbors fridge and computers as well. I live in an older house turned apartment. I tried the DIY AC filtering before from the Magnan site and it definitely helps.

Hello,

Here's another bunch of DIY mains filter ideas none of which I've tried but hope to try something from the list down the road.

I am currently putting a little 5f2 mutant together and i've put in a RFI filter made up of a couple small Miller chokes (5230-RC) and a couple 100n X2 type caps. Hopefully that will stop the pops from light switches, the stove, the furnace switching on... etc.

The filter is made up with one cap across the two power leads followed by one choke in each line then a second cap across the two lines. May also put an MOV on the power switch.

Take care

It would be neat if there was a power conditioner kit out there.

Anyone know of one?

If you just hung the components from the IEC connector, would that provide the same level of filtering?

[paulster]

Unless I missed it that article didn't seem to mention that the cap between the phases (the 0.1uF on Normster's drawing) should be a Class X cap, and those between the phases and earth should be Class Y.

Otherwise it's like going back to the 'death cap' that everyone has spent years trying to get rid of, which would not be a good thing.

[Normster]

Sorry, I just dragged "ready made" components off my stencil. You're correct, .1uF x-type, 2n2 y-type.

Hey Norm

I wasn't criticising you (the drawing is good), but the http://www.magnan.com/doityourself.html article itself that mentioned which caps sounded 'good' in this application but made no mention of the safety requirements in order not to end up potentially killing yourself after a few mains spikes have caused bridges across the dielectric. And, in fact, the caps they recommended were not X and Y classes.

I'm using IEC plugs with integrated filter circuit in all of my amps, like you may see on the left in the photo:

There even are two inductors included, in series with the line & neutral.

Yes, I have seen those IEC modules before and have wondered about them.
Got any specs on them?
