Part Descriptions - Vector G08 Series Faq

PART DESCRIPTIONS

The following sections describe the different major assemblies of the Electrohome G08-003 vector
monitor. Before we delve into the different parts of the G08 monitor, it is important to discuss the
different schematics that exist. The best schematics to reference are included in the Tac/Scan,
Zektor or Star Trek manuals. These contain the schematics with the HV Regulator PCB, the Input
Clamp board and the Current Limiting boards. From review, it appears Electrohome made updates
to the G08 monitor, but Sega neglected to change this information in their manuals.
Below is a brief summary of the different manuals and their attributes. I have given some
descriptions an "a", "b", or "c" designation. The "a" signifies the inclusion of the HV Regulator
board only, while the "b" suffix includes both the HV Regulator board and the Input Clamp board.
The "c" denotes the most complete information on the G08-003 monitor.

Input Clamp Board
This small 1 ½" x 3" board is usually mounted on a thin metal support across the back chassis of
the monitor. This board prevents invalid inputs from overdriving the monitor. Without this board,
the monitor picture will be too large, so the board does some "trimming down" of the signal inputs.
The input clamp board is the first interface into the monitor, and plugs into the main deflection
board. Since it is screwed to a thin piece of metal, usually you will find non-conductive tape on the
back of this board to prevent the header pins from grounding to the metal. A detailed parts list of
the Input Clamp board is provided in Appendix A.
