As far as the pictures go, it looks like you're vaporizing too much cadmium. It could be that the cadmium temperature sensor is not working or became disconnected somehow, giving you the 'open loop' light. Also, this would cause the Cd heater to just keep getting hotter and hotter because the feedback sensor see's that the cadmium is not up to the expected temperature. That's just a hunch. That is a neat setup though! What year is it? The tube looks identical to mine except I think that big thing on the OC end of your head may be an AOM or something... mine doesn't have that, and it looks like your cadmium reservoir is sideways whereas mine is vertical. Also, my psu is just one unit rather than the three separate units. Another thing to think about, although I'm sure you've made sure everything is in the right spot, is that those little gray connectors are what control the systems in the head (cd pressure, tube voltage, He heater, etc etc). Is it possible that some of them have been mixed up? It looks like you have about 4 different grey connectors there. Does only one come from the head?
It could also be that the head needs more helium, but this is rarely the case as the He reservoir leaks a tiny bit in storage, usually causing a bit too much He pressure. Is the He heater plugged in?
