Hard to believe now that music once came on vinyl records, small, medium, and large in size. And to listen to music on anything but a radio, that meant acquiring a record player. In those old days of 64, all anyone with ears wanted was a MacIntosh amplifier and preamp as the clarity was so remarkable. You could spend a ton of money and buy one assembled, or for a lesser amount of money MacIntosh offered a kit with parts that you could assemble yourself.
All to listen to the New Lost City Ramblers warble,
"Here's an old lady hanging out the wash
And now she's hanging a macintosh"
Chris Strachwitz likely couldn't afford the new UHER tape recorders that folk loricists from universities used for some of their field recordings and oral history projects. They were smaller, more portable which meant more easily transportable, and resulted in astonishing sound quality. Those were very expensive items. Almost nobody could afford those. Eventually Frank Zappa had one.
