Hi Folks,
I now have the service school books for the ES-IV, V, V.1, and VI available for free download along with tips on rebuilding the NSM keypad keyboard here:
flippers.com
NSM jukebox technical tips <#>
🔗 https://flippers.com/NSM.html https://flippers.com/NSM.html
Hope this helps!
Check my other jukebox pages for lots of service bulletins - use the pull-down menu "Service & Tech Tips" at the top of each page.
