Something similar to this.

I know I can buy one but it's probably cheaper to buy some X2 capicators and make it myself without the casing though.

Thanks for the reply.

Sir:

You should go through HeadWize Library and pick up a thing or two about mains filter yourself. Most of the things you need to know are ALL there.

Also, you will have thousands of articles on internet about PSUs if you go punch in "Power Supply Design Schematics" or something identical in nature at GOOGLE SEARCH.

P.S. Your links don't work.

thanks for the tip Tomo.

Well the problem with google is that you must supply a proper search criteria. I did try it but I didn't get anything good. It could be because I didn't use the proper criteria.

Something like this?

Hey,

Try using common mode filter. But then, I do use Corcom models and they work fine.

Follow this link for an article.

Note also you might want to use Interference Suppression Capacitors.

P.S. Note that CoilCraft is very interesting company. You should go through entire site. (They offer sampling ... But don't abuse it.)

I concur with Tomo wholeheartedly on this: the Corcom filters do the job well and are very reasonably priced. I doubt very seriously you will be able to duplicate, much less better, their performance by yourself.

Do you mean IEC filter?
It is around $10.

When making a DIY AC line filter, must I put it in a seperate enclosure? Also can I use a PCB?

Thanks

Hey,

Any AC stuffs should be near amp board. That includes transformers, etc. Sometimes it doesn't matter but it doesn't hurt to keep them away.

Yes, you can use PCB to build filter.

I use Corcom 3VK1. This one can deal 3A 120/250VAC. Very good stuff.

You can use the model where the unit is installed with the 3 pin socket like the one for the computers. I like this design and I will probably start using it after I run out of 3VK1.

Please note that when you bolt magnetics like this and trannies, keep the hot electrodes well covered. It is very "ouchy" to unknowingly electricuted. Personally, I don't need recharging

I've been electrocuted before and it's a feeling I wouldn't want to experience again.
