"Somebody gave me a c. '68 clock radio that cut out after 20-30 minutes of playing. Obvious symptom that some component had thermal issues. Simple to get a can of spray coolant and selectively spray things until I found the one where it started playing again. And ten years ago there was still one place in our metro where a retail customer could walk in and find a generic replacement audio output transistor.
"I don't make a living having anything to do with electronics. And I think you will agree that methodically spraying a can of coolant around a chassis and noting what component was bad on the schematic inside the box honest to God ain't rocket science.
"But anyone I tell about the repair looks at me like I'm Einstein or something. And that's what I hate. The way everything from appliances to philosophies are packaged today to promote helplessness, kill curiosity and foster dependency on 'experts'."
