The REAL filter kit build video.
Added 2020-02-03 01:02:25 +0000 UTCThis seems to be a common kit on eBay. I've included an eBay search link in the description, but keep in mind that China is in the middle of an epidemic at the moment. In the meantime you can buy similar modules built to local standards from most big electronic component suppliers.
It's a fairly common filter arrangement with design features that hint at it being a less well designed copy of another design.

2020-02-04 04:34:31 +0000 UTCYou mention the MOVs might have been fitted because they looked like Class Ys. A blue 0.2" disc saying 471 would normally be a cap. In my early days of dealing with a chinese manufacturer, component colour was taken as seriously as anything else. But maybe the MOVs were cheaper! Price trumps everything.

2020-02-03 11:14:50 +0000 UTCI have have been waiting for four 100Ah LiFePO4 cells and a BMS coming from AliExpress sellers. They haven't shipped yet and now god only knows when they might ship. When they do finally appear I suppose I will soak them down with disinfectant though I know that is probably pointless. It is terrible what those people are going through. The costs to their businesses will be staggering as well. How much business must China do every day, and now it's essentially all shut down.

2020-02-03 05:47:52 +0000 UTCnice but, if your hi-fi need that.... it means you should get a better hi-fi because all the decent electronic products have a EMI filter on them and it's made by the brand for the product....

2020-02-03 04:05:16 +0000 UTCApparently a virus can't survive long outwith a host, so it should be fine given how long it takes to get here.

2020-02-03 03:25:09 +0000 UTCFeel free. I think there are quite a few phones out there with audio clips from my videos in them.

2020-02-03 03:24:10 +0000 UTCI just ordered a new phone case from China before I read the description. When it arrives should I soak it in IPA? Or maybe soak it and the postman and set them both alight? Or even just forget that I ordered it during a crisis in China and resign myself to the fact that I'll probably never see it? Back on topic. Was nice to see you doing your old style soldering videos - explaining how it's done etc. That is one of the things that got me stuck on your channel. I have small hands but always do the same as you - hold the board and component and solder in one hand and the iron in the other.
