The left board as shown is the H shift and focus/G2 board. The focus block is
the same as used in other Barco 80x series of sets. The G2 control is the same
as the Barco 800/801, depending on what tubes are used in the set. These boards
don’t fail too often, but the G2 or focus blocks can fail and arc to the low
voltage sections of the set, causing havoc with the focus section.
The middle board is the horizontal and vertical sections of the set. There are
few user adjustable controls on this board, but the R and B master V height
controls are located on this board, located near the bottom of the above
picture, and the H width coils for each CRT are located near the top of the
board. Use a non-metallic screwdriver to adjust these coils. Under normal
conditions, these coils do not need to be adjusted.
