Title: Whats the best / cheap way to get clean AC?
Post by: SILVERGUN on November 05, 2012, 02:33:44 pm

My amp workbench is at my shop where we work on welding machines and I never really was concerned about clean input power before...
Now that I have an amp built I'm noticing electrical noise, from transformers, fluorescent lighting that is everywhere throughout the shop..

Is there a good inexpensive way to just clean up the power at my bench?

You can try to use a filter scapped from a UPS supply (those usually are big)

and connect it to your bench outlet

this for the noise coming from line

the irradiated noise can be stop only using shields (as far as I can know)

Unplug all the welders.

Otherwise.... no. There's stuff you can try, but is likely to be disappointing.
