Most old time radio and TV service guys didn't use a scope. If only for the simple reason that they were expensive. The more affordable scopes of those days had limited capability and weren't the easiest of things to use. Most faults could be found with an Avo and experience, without need for a scope. Component substitution was a common method of faultfinding. A signal generator and signal tracer helped to find trickier faults.
The time scopes became essential was for colour TV. It's more or less impossible to troubleshoot a decoder without a scope.
Like Mark and Trevor, the scope is almost part of me. It sits front and centre above the bench. Whether it's a simple 20MHz Hameg (Late 1960s TV service guys would have killed for something as good as this at an affordable price), my 400MHz Tektronix 2445B or a Rigol digital they all do a myriad of jobs with ease.
