The Hallicrafters S-107 receiver is a 6-tube general
coverage set which receives from 500 KHz to 30 MHz,
plus the 6-meter ham band. It was built in the late
1950s and early 1960s. It has a BFO for SSB/CW
reception, but no AGC (so you have to ride the RF
Gain control all the time!). It has a built-in 4"
x 6" speaker in the top of the cabinet. I spent
countless hours tuning the airwaves on an S-107A
as a young teenager.
I currently own the S-107A shown in the photo.
