Guys,

I'm stuck with an XPS-10S or 16S supply that will get up to strike but doesn't run.

It dropped dead during a show last night.

Last night after it dropped the current was a little low but we were still seeing dc on the console voltmeter. Today I noticed there is no voltage coming up when the lamp is turned on.

Only physical thing I observed was the positive lead to the filter caps burned off at the terminal. Replaced that and have good continuity on the neg lead but still have 0 no load to the lamp.

Any suggestions while I wait for someone more experienced to be available to fix this thing?

Right after I posted this I realized something I hadn't thought to check before: the failsafes on the lamphouse.
This is the one Xetron console in the entire chain that doesn't have them entirely bypassed or removed.
No voltage through the rectifier because the back cover was off. Duh!
