50 years ago, as an apprentice, I built 2 oscilloscopes (single channel with tubes). There was no way I could have afforded a purchase. Since than, I built many more pieces of test and (primarilly) audio equipment. The advent of sophisticated PCB design software and, later, inexpensive or free modelling software changed so many things
I now rather restore an old piece of gear (I'd do Healey 2000s if only I still had a garage). But I still build stuff because I enjoy the experiences of investigating, learning, bulding, testing and all the bragging rights that go with it! E
