I have a subscription pinball repair site located at
http://www.pinballninja.com and the site includes over 700 game specific repairs, which are categorized in a table of contents for easy searching. Also there's about 150 HD videos on pinball repair there too.
To get a userid normally a $20 or greater donation via paypal (as described at http://www.pinrepair.com/donate ). For a limited time, a $15 paypal donation is all that is required to gain access to the site.
Thank you and please feel free to email me with any questions.
