Lately, I’ve been restoring a Dynaco ST 150 stereo amplifier. As my collection of classic vinyl recordings grows, I’ve assembled the ultimate 1970’s playback system. Coming of age in the mid-70’s, I coveted the then-new high-power solid state amplifiers.
Christmas gifts for my two great-nephews are always a challenge, and with one entering the first grade, I wanted to up my game a little. The standard Lego-based gifts are always popular, but I sensed that something more involved might be a real hit. By the time I was in Grade School, I was fascinated by all things electrical and radio, so why not give them a crystal radio?
