Griffith Park Images
A post card of the Griffith Park Observatory coil, as it appeared in
June, 1967.
This is an 8" X 10" black and white photograph I took of the
coil,
while visiting in 1966. The camera, a Speed Graphic 4" X 5" press
camera, was being hand-held. The shutter stuck in the open position
producing the strobescopic effect.
A close-up view of the non-synchronous rotary spark gap, that
operates the Griffith Tesla Coil.
A partial view of the large glass plate capaitor bank, that completes
the tank circuit of the Griffith Coil. This stack of glass plates,
measuring about 20" X 30", was constructed of some 40 individual
plates of glass, each being 1/4 inch thick. This capacitor lasted
for some 15 years, before it had to be replaced with a more modern
construction capacitor. Before the glass plate capaitor, the
Observatory utilized the original Layden Jar units, that were part
of the donated equipment given to the Observatory.
