When you have completed your project, would you consider writing it up for publication in CQ-TV the journal of the BATC www.batc.org.uk

G'day Brian. Thanks for the info. I made a bit of mistake with my question though, it wasn't the Mixed Sync I was meant to ask, it was the Mixed Blanking In on the video amp board, I would like to know where does the mixed blanking in come from as I see no mixed blanking output lines coming from anywhere else to input to Mixed Blanking In? Does it possibly come from the Mixed Sync line? I know there's a blanking line coming from the 4011 chip on the timebase board and a blanking connection from the vidicon tube, I assume those two go together?
Anyways I'd be more than happy to write a publication for the CQ-TV journal once this project is complete and operational, thanks for offering me the opportunity!
This project is a warmup project to get me more familiar with camera electronics technology as I've previously mentioned I want to build a solid state driven 3 inch image orthicon tube camera.
I've now featured my project on my website, it can be viewed here

Lastly to answer old_tv_nut's question I got the schematics from the Amateur Television Handbook which can be downloaded here
