Instead of using #86 bulbs with the diodes and drilling of holes, I
used #84 bulbs. These are bulbs that have the same profile as the #86,
only require 40 mA (or .04 Amp) per bulb! Thus the total power
for four bulbs will be approximately 1 Watt! I noticed when I was
the clock, that there is about a 1/8th inch gap above the back wall to
the top of the clock. I don't know if this was intentional, or if it
was added on the later version of TZ, but it should provide enough
for 1 Watt of power dissipation. I must state that the light intensity
of the clock is considerably less now. However, I prefer the lesser
light; it gives the clock a mysterious (ghostly) feel as opposed to a
bright happy feel. Somehow that seems more appropriate for the Twilight
Zone theme. As I recall, most of the TZ TV episodes were dark in
BTW, the #84 bulbs also have a 20,000 hour life expectancy. Also, you
still add the diodes and reduce the power usage to 0.5 Watts, but I fear
the intensity of the light would suffer too much.
Another thing that I did to my clock to try and reduce the noise from
gear chatter was to use a lithium based grease on the gears and gear
posts. This seemed to have worked very well, as I can barely hear the
running now. Before, the previous owner used a light machine oil to
excess, and it actually leaked out of the clock onto the play field.
I had to fully dismantle the clock to clean up the nasty oil and apply
the lithium (white) grease. The grease should have a tendency to stay
the gears and not leak out of the clock. Also, white grease is
in nature than machine oil. I'm a little upset with myself for not
the white lithium grease on the moving parts for the gum ball machine,
didn't think of it at the time. BTW, if you didn't know, the hardest
dismantling a TZ play field is doing the steps for removing the gumball
what a pain.
