Parents had a big 1947 Magnavox console radio-phono: AM/SW with separate FM tuner; Webcor record changer; 15" field-coil woofer and ginormous horn tweeter (of course, the speakers were directly below the changer). When I was 17, the electronics gave up the ghost. My Father told me to find replacement gear, but it had to fit in the console. The only equipment that would fit was Dynaco. So, we ordered the PAS-3x and FM-3 built and the Stereo 70 and an EICO AM tuner (so my Mom could listen to baseball) which I built, a Dual 1009 and an E-V 15" full range. My dad bet me $20 the amp wouldn't work when I finished (thanks for the vote of confidence, Dad) but it did. Shortly thereafter, we bought an E-V speaker system for the second channel. The system now is in the hands of my nephew who is rebuilding the ST-70 - I wanted to but am so shaky, I didn't want to risk trying to install a new driver board. That was our family's first stereo.
