Ballast & Power Supply

It is a tight fit, but the ballast and
power supply can be fitted in the
base of the Specto. It will help if you
mount on it a thin piece of
aluminium by using tapped screws
from the old power terminal
previously used for mains tapping.

I have a switch (LAMP 1) in the
lamp circuit so the lamp does not
come on until this is switched
on.

When this switch on, the dowser
must be used as the lamp will come
before the motor starts and damage
the film. The Specto switch is
rewired to operate as follows:

OFF – Everything off
ON1 – Auxiliary fan
ON2 – HID Lamp (wired in series
with LAMP 1)
ON3 – Projector Motor
