There is far more access to diy audio supplies than in the day of Radio Shack, partsconnexion and parts express, amongst many others
For sure! But what Radio Shack offered you was a range of possibilities you could touch. You could be enticed by dozens of different electronic subjects in half an hour. We lack that in person store browsing experience. Of course, I can go online and order custom made speaker drivers made from Swiss cow bells now and pay in Bitcoin or Eth, but nothing comes close to the Shack.
