I ALWAYS add extra earth to EM games i own.. mainly to the transformer when i replace twin cable with 3 core and then to coin door etc. The legs are isolated so no need to earth off, but if wiring especially the ( now) 240V runs against metal it gets earthed.
GTB coin doors are a MUST
Is that all GTB or just EM's?
+1. I know time is precious but it might be a good thread to start up showing some pics of what owners of older Gtb machines should do to make their machines as safe as possible. Please.
