My Dad.
He had 'listened in' when at boarding school during the 1920s at the dawn of radio before there were any commercial or entertainment stations. Goodness, that's 100 years ago. He built crystal radios from components or kits and as soon as something better came out he sold his to a schoolmate and bought the improved model. He frequented Lisle Street in London's West End where all the radio shops were then, before the glory days of Tottenham Court Road in the 60s and 70s.. It's part of Chinatown today.
After the war he bought surplus shortwave radios that had been in warplanes. Even into the 1970s he used one as his main radio to listen to the BBC.
In the 1950s he set aside his large gramophone cabinet with a Garrard autochanger inside and started buying audio separates. By the early 1960s I was using these to listen to my Beatles records and so on. When I was 14 I bought my first system, a Garrard HF and Rogers integrated amp and tuner. He lent me two of his old speakers from his mono years, a Goodmans and a Wharfedale - yes, they didn't match. I have spent the next 60 years moving onwards and upwards.
My dad passed in 2012, at the age of 102. Because of failing hearing he had stopped using his hi-fi about 7 years earlier. That system was mostly my hand me downs. What goes around comes around.
