Sure they do. It's different in that you get a shock that can burn right to the bone and cauterize itself so it doesn't bleed. Got lots of those. Yep, good times. Still get whacked mostly by power supplies that hold 400V across the PFC cap for a couple of days. Those will get your attention. |

This detailed article by Rod Elliot explains why using an iso is hazardous - not that reading it will have the slightest impact on wooden heads like you or NT. http://sound.whsites.net/articles/iso-xfmr.htm FYI: The use of an RCD, ELCB or other earth leakage detector ( aka safety switch) on a workbench is a safety essential. ....

I fixed lots of TVs with no such 'essential'. Most were live chassis. Any sensible person would advise using one now, but essential? We just used what was available & affordable at the time. NT |
