DC power on Tesla Secondary - Nasty Arcs

["Tesla list" <tesla-at-pupman-dot-com>]

During the RATCB teslathon, there was an individual who had a DC source
connected directly to the base of the secondary.
The result was some serious nasty-thick high voltage arcs coming off his
toroid with the DC applied.

I was wondering if anyone had more information how this DC was connected
/ buffered / filtered as I didn't get the chance
to speak with the individual at the time.

Thanks
