Ah..... Ozone! [Linked Image]

I smell it more out of the back of TV sets when the EHT has been arcing at the CRT connector or the LOPT. In a darkened room you can see the lovely blue-ish corona discharge too.

The smell also hangs around in parts of the London Underground, particularly on sections where sparking at the conductor rail is prevalent due to the track layout. Always takes me back to riding the trains as a kid! [Linked Image]
