Got this game running on Sunday . It plays pretty well . 
Found 1000's relay was continually held on because switch D on Player relay was out of adjustment (closed for player 1 instead of open) Also had a couple of playfield switches not working because I had somehow missed screwing them in after the playfield swap.
Neither POP bumper was working due to badly pitted spoon switches which needed some major filing .
Still have a couple of gremlins to iron out .. 100,000 light for player 2 is always on and about 1 in 20 games nothing happens when hitting the start button (suspect game over relay not latching due to a mechanical issue)
Now I will need to have a stab at touching up the back glass .
Good to hear you’ve got it playing again. I played a Space Odyssey for the first time recently amongst a very large selection of games and it really stood out as one I enjoyed playing the most.
