Hi All! I have a Weller PUD81 solder station, everytime I switch it off I can hear a powerful "bump" in my pc speakers. To solve that problem I want to put in parallel to the Weller switch a snubber. I need some help about R and C values. The Transformer inside is 95W. Thanks all! Simone |

I can't say exact values but you can start with 470 R (1-2 W) and 0.047-0.1 uF X2-type cap. I think loud bump mean bad design of your PC speaker power supply too. |

Thank you for your reply, I’ll do some test... the speaker psu is a toroidal transformer with a rectifier bridge and some capacitor... I don’t have an EMI filter on the AC line, maybe this can be the problem... |

Try using a different AC mains socket for the soldering iron. |
