Hi too-many-pins
I did a search https://pinside.com/pinball/forum/search?s=1&what=topics&q=outer+space&topic-machine=&pinsider=&age_days=&subforum=0&sort_by=date&sort_order=DESC#results (first I do search "for the name of the pin" in the topics-Title - then a search "for the name of the pin" in the text, posts --- hooray, in here https://pinside.com/pinball/forum/topic/1972-outer-space-start-up-issue snippets of the schematics are shown - in post-2, last snippet I read "B10904 Transformer 115V., B10932 Transformer 230V." --- I show here an old JPG "Transformer on my 'Orbit' " - the schematics say "same transformers as in Outer Space" --- see in the middle of the JPG "bakelite stuff, Adj. Plug, my green V1 V2 V3 V4 V5 V6" --- the (230Volt) Transformer B10932 can be adjusted (bakelite plug moved-left-then-plugged-in) to run on USA-115Volt-currency. Greetings Rolf
