Using Osciloscope on Hot Chassis

[Tubejunke]

This is great. Now I am going the right direction. The GFI is great anywhere in a shop or home, but I currently have none installed. I need to, but this isoformer is a must with all my "American Five" radios and at least one early 50s Motorola 17" television with hot chassis. I can't believe I have gone decades now without an isoformer! Geez!

All my GFCI's are permanently installed, but I made a few portable ones, using a power cord from a scrap outlet strip and a plastic single gang box, to use my power tools, where there is no GFCI available.
I've been using them ever since they came out.
It also saved a few headaches from accidental damage to a hot chassis set, when I bumped the heat sink with a cable TV connector. They respond that fast.
