Return of the Jedi - fixed
First easy fix I have had in years, found a bad graphics ROM when I inserted it into the EPROM programmer and it immediatly reported several pins as bad :)

So the Centipede monitor was driving me mad. I had fixed the monitor, but it was making some pretty nasty arcing noises. Originally there was some tracking around the anode cap, as the original lopts lead and cap were badly worn from previous arcing problems. I fitted a new LOPT and the tracking around the cap stopped, but it was making some even louder arcing noises, but I could not see any sparks even in a dark room.
Due to time constraints, I gave up with the first monitor and moved onto a second monitor (Euro MTC900E) which had bad vertical deflection and the red drive stuck on, both faults were reasonable easy to fix and the monitor was working, sat on the floor in the garage wired up to the back of the Centipede cab. I proceeded to fix the rest of the cab (such as stripping, cleaning and oiling the trackball, performing the AR2 sense mod on the power supply, cleaning up the cab and fitting locks) and I fitted the monitor into the cab. When I went to adjust the picture on the monitor, I noticed that the monitor was now making cracking noises...... Arrrrrghhhh. I don't know if it is the cold weather or I am just being damn unlucky or what? I am running a dehumidifier in the garage, so there should be no damp air. Anyway, looks like Centipede is not going to make it to Replay, I still have other stuff I need to work on. I will re-visit Centipede if I get time, but it does not look promising at the moment.
