In 1992 to 1994 Barco introduced the 700 and 701. These were primarily
designed for the home market as the case was small and very streamlined looking.
The 70x series started with the Barco Vision and Data 700 models. These sets
used Sony SD 187 tubes that are also found in the Electrohome ECP projectors,
some Sony 10XX series and the Barco 400, 500 and 600’s. The tubes are ES
focusing (on all Barco 70X series) and produce 600 lumens. The Barco Vision only
scans to 36 Khz The Data version scans to 50 Khz.
The 701 set is a bit newer than the 700, and uses the later model Sony 07MS
tubes that put out 750 lumens, and are a bit sharper than the older SD tubes.
The component layout of the 701 is similar to the 700 and some boards are
interchangeable between those two sets.
The Barco Vision and Data 701s sets came after the 701. The difference here
is that the 701s sets used Toshiba tubes that put out 1000 lumens, quite bright
for such a small chassis. The Toshiba tubes also can be rebuilt, the older Sony
tubes cannot. The circuit changed slightly from the 701 sets, and the 701s can
accept a component input without the use of a transcoder.
The 708 is the latest version in the 70X series with some upgrades to the
chassis. It's also about 2 years newer than the 701s. The 708 has some circuit modifications done to make
the chassis more reliable. The 708 also added the IRIS auto convergence camera
as an option. The Data 708 also increased the max H scan frequency to 69 Khz.
The Cine 7 replaced the 708 in about 1998. Again, minor circuit changes were
made, and used a slightly better version of the original Toshiba tube made by
MEC. The MEC tube is more expensive than the Toshiba tubes, but held the
focusing ability for a longer period of time.
The Barco 70X series are great performers for such a small set. The problem
with these sets is the close proximity of low voltage boards carrying video
signals to the high voltage areas. Any kind of arc within the set, and there’s a
reasonable chance that a board or two will be damaged. Fortunately, some of
these failures are easy to diagnose and relatively inexpensive to repair.
