I grew up reading radio shack catalogs and dreaming of cool stereo's and radio's. . As I got older I made speakers out of cardboard and tape and put transistor radio speakers in them. I made them look like the real speakers that were full sized the best I could.
As I got older, (like about 11 or 12) I went to radio shack and got my "free battery per month card" I then saved up to buy a small transistor radio. When I was 14, I had a part time job and worked for a nice used home system for my room. Pink Floyd was the band for insane volume levels when the parents were out.
This is my mini collection today...
And I still enjoy going through the old catalogs.
