MAKING THE MONITOR MORE RELIABLE

Ok, so now you have a working G08 monitor (hopefully). Here are just a few things you can do to
the monitor to prolong its life just a bit longer.
Input Clamp Board Modification
Replace the tape on the back of the input protection board with a strip of electrical tape or other
non-conductive material to prevent it from shorting to the metal bar it is typically mounted on.
Deflection Board Modification
For capacitors, see "Installing A Cap Kit" section of this document.
Deflection Transistors Modification
From Zonn Moore:
The biggest problem with the Sega G08 is the underrated Deflection Transistors (the second
biggest is all the proprietary Ics). To fix the transistor problem you an do just what Rick suggests.
Parallel two power transistors for each one currently being fan cooled.
The thing to do is to get two of each transistor, connect the bases and collectors together. Then
connect a resistor from each emitter to the place the old emitter used to go...
