Sixty years ago this month, the July 1965 issue of Electronics Technician carried this ad for a useful product from Sprague Capacitors, the “Quig”. It was for making connections for replacement components in tight spaces. It was essentially a solder-covered spring. When removing the old component, you would leave part of the lead in place, slip the Quig over it, and then slip the new component into the Quig. With one hand, you could hit it with the soldering iron, and be done with the job.

As far as I know, the Quig no longer exists. But for replacing components in old radios, a similar method is employed. You leave a portion of the old lead, and then wind a little spring on the new component. You slip that over the old lead and solder it in place (with two hands).
