Williams System 3, 4 and 6 #D-7999 Power Supply.
Meticulously crafted & re-engineered to suit Williams System 3, 4, and 6 machines.
This power supply is designed to replace the ageing Williams D-7999 power supply, with it getting hard to find replacement axial type capacitors & the high voltage transistors not having a modern replacement, we have come to the rescue with our version, we have used latest technology switching 5 Volt in the traditional To-3 package, with ease of future maintenance in mind, up-dated the high voltage transistors to above industry standard, opted for heavy duty box headers for those plugs that always get hot & burn.
Key Features:
Modern Low Voltage System: We’ve redesigned the power supply to utilize common modern components, featuring a switching 5 Volt regulator, snap-in type capacitors, beefed up from 12000uf to ( 2 x 10000uf ) total of 20000uf on your 5 volt filter system.
Modern High Voltage System: We’ve engineered the high voltage section to utilize common modern components, along with the industry standard dropping the voltage to 91 volts to give greater life to your aging plasma displays.
Corrected Design Flaws: The original Williams System 3-4-6 power supply #D-7999 contained design flaws that were only addressed with the System 7 power supply. Our updated version corrects these issues, along with modern components, bringing the performance & safety of our power supply up to the standards of Systems 7, 9, and 11.

Fuse F4 is not included. Please refer to your game manual for further information.
