Fifty years ago, the August 1974 issue of Popular Electronics offered some pointers for hobbyists thinking of going into business for themselves repairing televisions. It reminded that in some jurisdictions, a license was required, and that high voltages were present, so you had to be careful. But for those who wanted to ease their way in, the initial investment might be as little as fifty dollars for a set of tools, and the most common tubes. As you eased your way in to the business, you could upgrade, and the magazine gave recommendations for the parts, equipment, and chemicals you should keep on hand.

The magazine also reminded that in some cases, the experience and test equipment required might be out of your league. Therefore, if possible, it was wise to make a deal with a full-time service shop to tackle the jobs you couldn’t handle.
