When you go into RS for an emergency part, go straight to the parts bin to look. But more and more lately when I've asked about something, the floor staff was informed and could answer my questions. Depends on the store, I guess.
RS, Lafayette, Olsen, BA -- all great memories, not to mention WRL and Walter Ashe. Every time I got something at any one fhem I wished I could have afforded the same part from Allied. But the others usually had that "4 for a buck" package schpiel & with my budget back then, that dictated RS or one of the others. And, yes, both RS and Lafayette on Comm. Ave. in Boston were FAMOUS for "No, but we can order it." Yea, right. The first, and last, time I ordered anything I got a completely wrong order & had to wait even longer.
In Pontiac, MI, we had Electronics Supply. It was primarily a wholesale distributor for TV repairmen, but the owner liked hams, even tho' he wasn't licensed, and if you had a ham license you could shop there. With a Novice or Tech license, you could buy stuff that was directly involved in transmitting and receiving. As a general or above you could by anytihg...like Police receivers...UHF TV Converters...FM tuners for the car, etc. He was a great guy. His main hobby was Stereo Realist photography and was famous for his 3D Slide shows. They were great!
