Is anything besides the transformer getting warm ? This is where a laser thermometer is very handy.
How dirty/dusty were the PC boards ? In my garage it's possible for metal fragments to get everywhere. Try brushing/vacuuming/blowing w/ compressed air. I know it sounds gross, but sniff around for cat pee. I've had several things sprayed. Any chance you are running at 240V ? If the transformer is set for 120VAC that will cause overheating. I've never had a traditional power transformer fail on me unless something happened to it (water damage, overloaded) I suppose it's possible for the laminations to develop a short/leak. Only way to find out is to remove the transformer and bench-test it out-of-circuit. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
