Right about most of it.  The Regency TR1 was intro'd in 1954. 
In terms of sensitivity, picking up powerful stations was just about the 
ONLY thing it could do.  Transistors were pretty unreliable quality, and 
the only way you could make a decent set was to use 7 or 8 of them.
Regency used only 4, so the result was poor sensitivity, and low audio
level.

Pretty awful receiver, but it's worth a bit, since it was the first.

BTW, anyone have one they want to sell?  Am looking for one!!
