—No. 1458 lamps, in case you are wondering, are found in Bally 50
volt gambling machines (race horse, one ball games, etc.). They
create an immense quantity of heat.
If I owned such a game, I would
consider rewiring the circuits to accommodate a 6 volt lamp.
Since replacing lamps behind the backglass on early machines in
volves removing the glass, a cautionary note is necessary. Before
sliding the backglass out the top of the lightbox (remove the top
molding), check to insure that there is sufficient clearance behind the
glass. Clearance was tight when the machine was new but the light-
board often has warped. If this is the case, the ink will be scraped
from the glass as it is slid upwards. The glass will be ruined. If neces
sary, loosen and remove the screws on the side of the cabinet or in
side the lightbox that hold the lightboard to the case and move it
back away from the glass. The glass can now be removed safely.
Before reinstalling the glass, it is desireable to remount the lightboard
with greater clearance. This will have the added benefit of spacing
the hot lamps further away from the glass.
One more tip will help replace lamps in recesses in the lightboard
where there is no room for fingers to grasp the bulb. Find a pencil
with a large plastic eraser holder rather than a metal holder. Carefully^
remove the eraser from the holder leaving a cup on the pencil. This
will fit over A and B style lamps in most cases, providing an extension
to your fingers. A small piece of dowel with an appropriately small*
diameter piece of rubber tubing attached will accomplish the same
effect. The fit should be tight on the lamp to be removed.
These instructions and precautions sound complicated and involved.
They are really quite simple and necessary. What price would you
pay to preserve the condition of the backglass and plastic artwork in
your machine(s)? Remember, the artwork is generally irreplaceable
unless someone can be located with a used backglass. Often that re
placement has not seen the best of care either, so care is the watch
word.
