Radial Capacitor
• Temperature, age, and humidity can and will change the original
values of capacitors. This is why capacitor kits (or cap kits) are
necessary.
• Always install capacitors using the correct polarity (positive to positive,
negative to negative). Installing a capacitor in the wrong direction can
result in damage to the electronic components, and in some cases
cause fire or injury.
• Some capacitors are Bi-polar (BP) or Non-Polarized (NP). These
capacitors have no positive or negative leads. It doesn't matter which
direction these capacitors are installed.
• Always remove any old solder before installing new capacitors.
• For best results, use high-quality capacitors like Nichicon or Panasonic.
Anode (+) = Longest lead
(positive lead)
Cathode (-) = Shortest lead
(negative lead)
Axial Capacitor
Note: Certain capacitors will not be available for all
the exact voltages listed above. It is perfectly
acceptable to use a higher voltage capacitor with the
same capacitance as a replacement. However,
use a lower voltage capacitor as a replacement!

General Remarks

• First and foremost, these monitors are difficult to
work on because of the availability of certain parts.
Since these monitors were made in the United
Kingdom, I guess it would be easier to find parts if
you lived in Europe. Be warned...
• Most aluminum electrolytic capacitors are rated for
at least +85C maximum temperature rating. It is
my personal preference to not install +85C
capacitors unless absolutely necessary on any
board. Since this is a CRT monitor, higher
temperatures will be generated if the monitor is left
on for long periods of time. I prefer to install at
LEAST +105C maximum temperature rated
capacitors (or higher) to help mitigate this.
• Starting on page 3, the "Voltage" column on the
capacitor list for each board states what voltage the
schematic calls for. The "Installed" column refers to
what voltage the capacitor I opted to install to take
advantage of the higher temperature rating.
• There are MANY different versions of each board
available for this particular monitor. Please pay
careful attention to what version of each board you
have. The version number will be silk-screened on
the bottom of each board. This wellness guide is
applicable only to the:
• Interface Board
• Deflection Board
• Neck Board
