Background - It started with the JJPMAC: With the new Wizard of Oz Pinball machine shipping, Pinnovators turned our focus on taking the audio control design a step further. The Wizard of Oz game gave users the ability to adjust the volume level of their headphones and the ability to mute the system speaker from the exterior of the coin door. The only thing missing was the ability to easily control the system speaker volume without opening the coin door during play. Pinnovators set out to design a simple plug-n-play kit that could easily be installed with minimal tools on the factory removable DBA door plate.   Kit Details: The kit includes our stock look powder coated DBA door plate with high quality/high reliability
