Ok ive just found out how the G08 monitor got its bad reputation. Before
I begin , this may be a bit long and my questions are scattered in
between, sorry in advance.
I have had in my possession 2 Star Trek machines. One dedicated and one
is a converted Asteroids. One has no monitor and the other monitor
worked but was "flaky". I also picked up a dedicated Space Fury three
weeks ago that also developed monitor problems as is was shipped across
the country, so the time came for some cap kits. The 110 cap kit that
Zanen sells is really off, in its selection of components. First, I’m
not real happy with the lower voltage caps supplied in the high voltage
area and what is with the deflection transistors? The original
transistors were MJS0003 but replaced with 2N6259 in the revision 03
monitor. Unfortunately, these are no longer made but NTE does cross
reference the 2N6259 to the modern transistor NTE388. The Zanen kit
comes with 2N3716. ????!!?? Is the really suitable? I also was amazed
how cool these transistors run. Very cool to the touch unlike the WG
monitors.
 Anyway, The caping of the monitors fixed the Space Fury monitor but
didn’t change the Star Trek monitor. I suspected that there is a failing
Fly back in the Star Trek as the picture fuzzes out and I think I can
here arcing (although I don’t see arcing) in the HV area. To prove this
out, I swapped out the HV unit with a spare and the HV problem went
away.
 I wanted to test both my Star Treks so I put the working monitor into
the converted ST and the picture was just gorgeous. But when I put it
back in the dedicated ST I noticed I have no blue???!!? I was poking
around when I heard the sizzle of burning parts and that familiar smell
of burning parts… Even the deflection transistor fan quit. Any one ever
had a similar G08 experience?
 Dont get me wrong, The loss of blue had nothing to do with the frying
of the monitor. This game has other problem as well like no sound
(though it did partially work when I picked it up).
 Ill be ripping out the deflection board tomorrow but if anyone has any
comments.. I’m listening.
