$2 DIY Hum Suppressor

Hum and Buzz is often caused by a Ground Loop in audio equipment. While many solutions exist at removing a ground loop or filtering out the resultant noise, the best solution aren’t always the cheapest.

In this video though we build a device that can help reduce the effects of ground loops and subsequent hum. Parts needed can sometimes be salvaged from old electronics for free, or like me purchased online for under $20.

Parts used:

Two high-voltage diodes; 6A 500V minimum recommended.
One 1K Ohm resistor
Power cable /w ground pin
Soldering iron and epoxy

While we do introduce some safety mechanisms, this build is not advised; the potential safety concerns of dealing with household power are significant. It also may be illegal to use in your region.

You build one at your own peril. This video is for entertainment ( and ASMR ) purposes, only.,
