SCTV Clock Assembly Manual 1/24/22 14
Cabinet Assembly
Introduction
This section describes the wiring of the clock controls and CRT, and the assembly of the clock into the
laser-cut Plexiglas cabinet. The wiring harnesses are made first, then the clock is assembled.
The wiring parts are packed in a separate bag. The wires are provided with pre-crimped terminals to
simplify assembly and assure durable connections. Do NOT insert the terminals into the connector shells
until instructed. If a terminal is inserted into the wrong shell hole, it may be removed by gently pushing
down with a 1/8" slot screwdriver blade on the little tang visible through the slot in the shell while
simultaneously pulling the wire gently out of the shell.
Each of the four control pots is soldered to a tiny cat-shaped PC board. Three wires from each pot are
terminated in two Molex connectors. The CRT socket has ten wires soldered to it, which are terminated
in two Molex connectors.
The cabinet assembly is the next step. The cabinet is made of seven pieces of laser-cut acrylic plastic.
The clock base is two identical pieces that are sandwiched together for added rigidity. The base holds
the PC board, the front and rear faces, and the cover. A bag of cabinet hardware is used to assemble the
cabinet.
The PC board is first mounted to the base assembly, then the front and rear faces are added to this. The
pots are installed and plugged in. The CRT socket is installed, the CRT clamp ring is installed, and the
CRT is installed. At this point, the clock is plugged in and tested. Then the CRT is aligned with the case
and its clamp tightened.
Next, the rear cup and cap pieces are installed (the tricky part). The cup is a small flexible piece that
protects the neck of the CRT. The cap is a flat piece that fits into the end of the cup. The front and rear
faces hold the controls and the CRT. Finally, the cover is installed over the clock.
Tools needed
1/16” hex driver or ball driver
Slip-joint pliers
5/16” wrench or nutdriver
#1 Phillips screwdriver
#2 Phillips screwdriver
Small file
Roll of duct tape or Gorilla tape (for peeling paper from laser-cut plastic)
Cabinet wiring parts
There is a bag of cabinet wiring parts provided, the bag with the wires. Check that all parts listed below
are present.
Separate the wires carefully by length, as there are six different groups of wires that are soldered to
different things. The pot wires have small gold Molex pins, while the CRT socket wires have large tin
Molex pins.
