27,000 uf 25V Atari “Big Blue” capacitor. These replace the OEM 26,000uf 15v to 28,000uf 15v that the games originally came with. Used in Williams Pinball Games and Atari video games. Atari Big Blue Capacitors are used on Atari power supplies. These capacitors are located on the power supply block/Brick on Atari transformers, and have screw down terminals. If your game does not have a new one and has strange problems with power or resets than many times replacing this can fix it. It is always good to replace the old capacitors with a new one as preventative maintenance. These are the exact size replacement 2″ diameter so they fit perfectly in your existing power supply without modifications. These include 2 brand NEW screws for the terminals. These are FRESH manufactured in 2017.
