Thank you so much for including me in this forum! As a young man in the 70s, our hobby was to cycle around town from stereo shop to stereo shop and collect brochures of the latest in HiFi. We looked at pictures, dreamed, and read data sheets until our eyes were big and wet! When college was on the agenda, I took a degree in electronics audio/video. Eventually, it became more education and a career in the sales of medical equipment and systems. Stereo systems and large speakers were replaced by a wife and children, dog, job and obligations. And so life has gone at a furious pace, until suddenly the children have become adults, the dog is gone, the job doesn't feel so demanding, and my dear wifi is still here, but I need a hobby! So the short version is that I went on Youtube and was completely fascinated by the large community of vintage stereo lovers, skilled technicians and the amount of equipment from all over the world that actually existed, and my old interest in hifi equipment was immediately brought back to life! So I got/bought some old receivers to be restored, brought out my vinyl collection, borrowed a turntable, my son-in-law came dragging a pair of old JBL L100s. So this hobby is fascinating, I love both listening in two channels, repairing electronics, learning a lot of new old stuff, and reading comments on diyAudio. Life is good 🙂!
