Thank you for your reply, I have had this project on hold for the past month now with no progress.
This evening I managed to get it to work after seeing a number people connecting the +5v to the csync on the voltar board with a 2.2k resistor as below.
@Voultar Genesis rgb bypass board in a late model 1 master system looks crisp and I don't notice any jailbars I used 4.42k resistors instead of 5.6k looks great thanks voultar also for the troubleshooting! pic.twitter.com/z8KGf3G84e

All of a sudden I have a signal on my OSSC and it is operational.
The colours are now vibrant, but there are huge vertical lines everywhere, I assume these will be corrected by swapping out the SMC components to the new values Voultar has suggested.
I bet if I tried your way it would have worked also so thank you for taking the time to respond.
