Barco 1000, 1001, 1500 and 1600. These are a series of 9"
analog convergence projectors that Barco came out with from
about 1989 to 1993. All very similar to the Barco 600 chassis,
but used 9" Sony ES focus tubes, called the SD-146A. A great
picture when properly set up, but Barco drove these tubes
quite hard, and sudden tube failures were common. These tubes
are hard to find on the used market, and are insanely
expensive if purchased new. 64 Khz scan rate, 1000 to 1500 lumens.
In around 1990, Barco came out with the 500 and 800 models.
The 500 is a 7" version of the 8" Barco 800. The 500 put out
600 lumens, the 800 put out 825 lumens. The projectors have
digital convergence which is very easy to set up, and lots of
on screen menus to guide you through the setup procedure. ES
focus on all of these sets.
In about 1993 Barco came out with the Barco 801. The 801 was
very similar to the 800, but had an extra circuit called AKB
that compensates for picture tube wear. Basically the same
overall picture as the Barco 800. ES focus on this set as well.
There are two versions of Barco 500 and 800 as well as other
Barco models. There are Graphics and Data models of most
projectors. The Data models use hybrid lenses and do not scan
as high as the Graphics versions, which also have all glass
lenses. The Graphics are somewhat more desirable, but in most
cases the scan rate of the Data projectors is more than
adequate for home theatre use.
The Data 500, 800 and 801 scan to 58 Khz, (line tripling), the
Graphics scan to 92 Khz.
In 1992 to 1994 Barco had a model called the Barco 700 and
701. This was designed more for the home market as the case
was small and very streamlined looking. 7" Sony ES focus
tubes, about 600-700 lumens, and scan rates varying from 36
Khz to 60 Khz depending on the model. This unit had digital
convergence, and a very nice picture if the tubes are in good
shape. This model was not as modular as other Barco modules,
requiring the projector to be sent in as a whole when
servicing was required.
A higher end version of the 701 is the 701s followed by the
708. The 701s and 708 used 1000 lumen ES focus Toshiba tubes,
and both sets came with component inputs along with RGB, video
In late 1993 Barco introduced a new series of video
projectors, the 808, 1208, 1200, 1209, and 1101. The 808 and
1208 were 8" tubes with the improved EM focus, the 1101, 1200
and 1209 used 9"tubes with EM focus. Many of these models also
had Data and Graphics models, with varying scan rates, and all
were rated at 1000 lumens or above. Digital convergence on all
of these models and lots of on screen menus.
Depending on the production run, the 808 either used Sony or
MEC tubes. The MEC\'s are rebuildable and the Sony are not. The
Sony tubes are at least $1800.00 USD each to replace, the
MEC\'s can be rebuilt for $600.00 USD each.
All of these sets give an excellent picture and have been a
popular seller when I get them in. I get far fewer 9"
projectors in, but the 808 and 1208 are usually in stock.
The Barco 808 was made until about 1998, and has been replaced
with the Barco Cine 7 and Cine 8. I have not worked with these
projectors as I have never had any in on the used market yet.
Very high end projectors though.
In general, the Barcos have held up very well, other than the
1XXX series as noted above. Barcos are very modular, and about
98% of the components can be changed out without picking up a
soldering iron. Most Barcos have a series of diagnostic lights
within the chassis that make it easy to narrow down the
problem area of a projector if it fails. I have serviced and
repaired many Barco projectors via email or phone, with about
80% of the projectors being repaired the first time I send out
Barcos are known to develop bad solder connections,
specifically in the main power supply area. The Barco 500, 800
and 801 have the unique problem that if a certain solder
connection fails on the power supply, all three tubes can be
burnt instantly. Once the solder joint is repaired however,
the problem never appears. I make a habit of resoldering all
solder connections prior to selling these sets, and any
