[SEL] WOW-magneto charger

[Harry]

Those are Tungar Bulbs. There are two in my unit and I think there are 
four used in the eBay unit to power both sets of poles. They must have 
had something special to charge with the poles 90 degrees apart and a 
switch is provided to select two or four. There is also a spare bulb in 
the unit being sold. I was able to pick up a few spare bulbs from eBay 
over past years.
