Well done mate... you need an EM game so you can learn EM games.. each different manufacturer has its own little quirks and twists. Williams I reckon can be the most troublesome mainly because of the positioning of the main relay banks and the tight switches. Now you've done a WMS you are set for the Bally Capt fant.. this should be a bit easier as Bally EM are easier to work on also.
Im also putting my Capt Fant back together soon.. so we could have 2 side by side threads here for a cracking title
