I'll try not to highjack MrBoat's thread but as long as we're talking about getting into electronics...
I kind of fell into the trade while going through uni. I had studied electronics in high school and even got to work with some low powered laser projects. Had a knack for it as a teen. While looking for summer employment after high school, a friend had started a business installing car audio in the rear of a stereo and TV store. I would come by after looking for work in the morning and started helping out with installations and then got involved with repair work. We eventually out grew the space and he got his own store selling car audio and doing stereo and TV repair. I hated repairing TVs
but liked to work on any kind of home or car audio equipment. We became the local Clarion dealer and authorised service depot for several brands. I also took some electrical engineering courses in uni but was basically self taught for repairs. We even had the Garry Robertson DJ service from out west bring us their gear for local DJs because they built their own equipment and there usually were no schematics to work from. I also got to service local truck weighing stations (on the side of the highway) when they first introduced sensors in the roadway to count axles and and get rough weight measurements. It fed a computerized system that ran the data and then used overhead signs to direct the trucks into the proper lanes. I was one of the few local techs at the time with both electronics and computer experience to diagnose those systems.
That job also helped feed my love for hi-fi. How can you resist when buying wholesale.
Mark up could be 50% to 100% back then so even during uni I managed to scrape up enough to get me started. I think my car audio system was worth more than the car.
First home speakers were a pair of Electrovoice Interface Series II like these
