Wells-Garnder Color Vector Monitor Guide Page 12 of 75 If you feel uncomfortable about poking around inside a running game cabinet, or you cannot 
reach certain areas of the monitor, there is a simple solution. Make a monitor ‘extender’ cable 
that will plug into the game harness. This way, you can have the vector monitor under test 
located several feet from the game and potentially in a better/safer working environment. 
 
NOTE: There is one small exception to the universal compatibility rule for the...

Wells-Garnder Color Vector Monitor Guide Page 13 of 75 INSTALLING A CAP KIT  
If you do not have a manual for this monitor, get a copy, as it does a good job of explaining how 
each section works and also how to adjust it. 
 
For those who do not like reading manuals, or who do not feel like locating local sources for 
specific parts or who do not want to hunt through a huge catalog to put together part numbers for 
an order, you can probably order everything you need (except for the upgrade parts and...

Zanens Standard Instructions: 
 
This monitor repair kit is designed for the Wells-Gardner 19K6100 X-Y color monitor, as used 
in Tempest, Space Duel, and other Atari color X-Y games.  
 
Be sure to install all the parts on the monitor even though many of the original parts seem to be 
working fine. Age, humidity, and temperature will cause the value of electrolytic capacitors to 
change. Also the other semi-conductors included fail often. Install...

THE REAL INSTALLATION/UPGRADE STORY  
 
When I ordered the Zanen #206 cap kit, I felt the instructions were rather brief and disorganized. 
There are over 30 parts to install on three PCBs! Which ones go where? These instructions 
should help correct that.  
 
Also note the Zanen cap kit #206 is based on specs for the original revision of the Wells-Gardner 
19K6100 X-Y Color monitor. There have been three revisions of this monitor, to address some...

CHASSIS TRANSISTORS 
 
All the monitor chassis transistors are mounted in a socket with two Phillips head machine 
screws. No soldering necessary; just unscrew the old one and replace. You cannot put these 
chassis transistors in backwards; the leads are offset so they will only fit into the chassis and 
screw down in one direction. If you put the transistors in backwards, the screw holes will not line 
up.  
 
Make sure you install a new clear...

DEFLECTION BOARD 
 
The Deflection board is the main PCB mounted right behind and below the monitor tube.

DEFLECTION BOARD (cont.) 
 
The following Deflection board parts should also be replaced, and are not included in the Zanen 
kit, and are not replaced by the LV2000. I would recommend installing these upgraded parts. 
These will bring your deflection board to the last revision created by Wells-Gardner.

DEFLECTION BOARD (cont.) 
 
To test the capacitors you will need a meter that has this option. Most do not, and the ones that 
do often will not go up to 4,700 mfd. If in doubt, just replace them, as they are relatively 
inexpensive. 
 
To test diodes, you must remove one lead of the diode from the board. Then put your meter on 
the diode setting. Put your test leads on the diode and note reading. Reverse the leads and test 
again. In one direction...

HIGH VOLTAGE 
 
The High Voltage PCB (in the metal cage with the flyback transformer) had several revisions 
too. I would recommend doing the upgrade parts here as well. This brings your HV PCB to the 
latest revision.
