Wow - thanks a lot! This was the inspiration of my youth.
I had fooled around with radios earlier, but my first hifi construction was the single-ended(!) transistor amp, p.51 Feb 1959; I probably built it in 60 or 61 when I was 13 or 14 years old. We were living in a furnished rental house that included a huge 15" hifi speaker; I had been given an assembled but non-working Heathkit tuner that a friend of my dad's had given up on. I fixed the tuner (a single bad solder joint - sound familiar, anyone?) and all I needed was an amp. Sounded fabulous, and made me an audiophile.
