6100 Monitor Low Voltage Section Regulator Upgrade
6100 Deflection Board LV Section Replacement Module The 6100 Deflection Board LV Section Replacement Module is designed to replace the unreliable low-voltage (LV) section found on the Atari 6100 vector monitor deflection board. This upgrade eliminates several common failure points that can cause instability, monitor shutdown, or inconsistent operation. Over time, the original low-voltage circuitry on the 6100 deflection board can become unreliable due to aging components, heat stress, and repeated power cycling. This replacement module modernizes that section of the circuit and provides improved reliability while maintaining proper monitor operation. Once installed, the module restores stable low-voltage regulation for the deflection board, helping ensure your vector monitor operates correctly in classic arcade machines such as Tempest, Star Wars, Major Havoc, Quantum, and other Atari vector cabinets that use the 6100 monitor. Key Features Replaces the original low-voltage section of the Atari 6100 deflection board Eliminates common LV circuit failure points Improves long-term reliability of the vector monitor Helps stabilize monitor operation and voltage regulation Designed for arcade restoration and repair work Compatibility Designed for use with the Atari 6100 vector monitor commonly found in classic arcade machines such as Tempest, Star Wars, Major Havoc, Quantum, and other Atari vector titles. Installation Notes Soldering and de-soldering are required for installation. The module installs directly onto the 6100 deflection board as shown in the gallery images. Installation should be performed by someone experienced with arcade PCB repair. This upgrade is an excellent solution for arcade collectors and technicians restoring original Atari vector monitors who want improved reliability without replacing the entire deflection board.

It is engineered to replicate the functionality of the original DIP package chip while allowing collectors and technicians to keep their vector-based arcade systems running. This chip is commonly used in Atari vector arcade machines where the AVG (Analog Vector Generator) system manages the generation and control of vector graphics displayed on the monitor. Proper operation of this chip is essential for stable gameplay and correct vector drawing.
