After the fit-check
above, I sanded
and painted multiple coats of white semi-gloss latex paint on the

the Playfield renovation.

that the whole assembly fit together very well.
the coffee table and final assembly
Once I was satisfied
with the initial
fit check in the unmodified table, I ordered a pane of tempered glass
(18.5" x 44.5") from a local
. It arrived after 10
days, and I then started the modification of the table by cutting out
the center panel with a circular saw. I then used a router to
create a 1/4" edge for the glass pane. I used a 4 foot level
clamped to the table as a rip fence to ensure straight cuts of the saw
The modified coffee table with the center panel cut out and an edge
routered for the
glass pane. I was very pleased with the result. It
like a picture frame for the
playfield. This coffee table was very close to the ideal size

made sense to me to light the General Illumination (GI)
On the actual machine, the GI circuit requires 7.8 Amps. Per
schematic, this is powered with a 6.3Vac transformer winding.
Although the current total includes the backglass and the coin door
lights, the test
allowed me to estimate the size of the transformer needed. I
purchased a 12.6V CT 4 Amp transformer from www.mpja.com
for $5.75. By splitting the GI consumption into two separate
4 Amp circuits, efficiency is increased . The two phases of
transformer power the two separate GI circuits on the playfield.
Using my Kill-a-Watt
I measured a total power draw of 30 Watts for the lights and the
transformer. The transformer only gets very slightly warm.

Pinball Neon Lighting
In November 2006, I bought a small neon sign on ebay for $37 (shipped).
The neon sign was installed at the bottom of the stairs that lead to
the game room.
I had installed an electrical outlet the weekend before in anticipation
of its arrival.
The light is turned on and off with the main wall switch.

allows it to be
wall mounted (holes in the base) or table mounted.
A switch in the base allows you to select flashing or constant 'on'
mode. We prefer the latter.
