While we are on this subject,can anybody recommend somebody who could repair or restore a nonworking tube tester?

It very much depends on the type of tester and, of course, its immediate condition. Could be anything from a bad rectifier tube (or tubes), to mice in the works. Or, as BBB suggest, a bad lamp or other wearing part. Could be dirt.

Brand, and model would be useful.

This would be a place to start.
