Soon after my wife and I got married, she used some of our wedding gift money to buy some lamps. We like them quite a bit. But one of them developed a big problem with flickering. I fixed it, temporarily, by bending the tab underneath the light bulb, but last week it deteriorated rapidly, ultimately reaching the point where any time we turned the lamp on, it blew the breaker immediately.
After trying a few things, the solution ended up being a $3.50 part similar to this one. Purchased locally, of course.
