30V seems to be the answer. I am going to attempt to repair the factory
switcher. I found one electrolytic gone and few other things suspect. So I
will know for sure. Model number (custom) suggests 30V as well. As to
manuals, I can go as old as 4040B, but not A. I do have an option of using it
with 24V external.

That shows the pre-regulator DC power requirements as a nominal 26 V, with a
range of 22 to 30 V.
I'm not sure how relevant this would be to the FTS-4040 but wouldn't be too
surprised if there are similarities.

Now it is certain the failure is power supply. I fed 26V into DC port and
everything is working as before. I'd rather replace this faulty supply.
Question is, 24V? 28V? 30V? or 28.45V? This power supply appears to be a
custom unit. Still looking for spec on power supply.
At least it's not the cesium tube....
