This is a fun and clean family game.
It was given a complete check up and Shopped, we remove all playfield plastic, ramps, light bulbs and posts, clean everything removed in the ultrasonic cleaner, cleaned all light inserts under playfield, clean the playfield and polish it, and then reassemble the game, check all switches for proper adjustment, and all new white bands, replaced all the bulbs, then checked them to make sure there are no shorts in the lamp matrix. Then we reassemble the playfield plastic and check switches and lamps again to make sure they work properly.
Battery was removed and converted over to a NVRAM by www.pinitech.com
These modules use CYPRESS F-RAM nvram ICs rated at 151-year data retention & 100 trillion reads/writes. So no more changing or leaking batteries very great idea.
