Old "Radio Shaft" catalog's online.
I must be an "Old Fart", I can remember when "Radio Shaft" actually sold "RADIO'S" !
Now-a-day's you can't hardly find a connector in some stores, and don't even ask for a 1N34 diode (you get the "DEER-IN-THE-HEADLIGHT'S" look).
And "NO I DON'T WANT A CELL PHONE" with that !
I also remember "Burnstine Applebee" (SP?) and Lafayette Radio stores as well.
And a Saturday morning trip to the south side of Indianapolis to "ESSE Radio" (big surplus dealer) was almost a must do thing !
