Yep thats the darn opto that’s giving me grief. I got in touch with the guy that sold it to me and he sent me a “new” one. I connected it all and only two of the opto’s worked. I then stuck in my original one and now none of the optos work????? arrgggghh.

I have ordered from ebay a new set of optos. Fingers crossed it works.



I have also replaced the broken Daleks that cover the bumpers. Looking very sweet.
