the life of an AC transformer.........
Hello...
I have an old photo studio speedlight (Speedotron) that is starting to buzz and overheat. Actually, it's the AC mains XFMR, but as the unit warms...and the transformer starts to bubble......yikes!, amazingly the strobe unit still works. I'm obviously in need of a new transformer. I know that old transformers tend to delaminate, but what other maladies do they suffer? Can they just overheat from failing insulation, or other aging issues? I realize rising current draw could cause similar behavior, but I'm assuming age as the factor in the transformer for now. Is this a foolish assumption? (25 years old) Les KA9GLW |
