Sontag Drug Stores was one of the largest drug store chains in the U.S. in the 1930’s & 1940’s. The one at the corner of Wilshire Blvd. & Cloverdale Ave. is now Wilshire Beauty Supply. Who knew...
Sontag Drug store. From a historic site "In 2021 we went through the process to declare the Sontag Building an....... Historic Cultural Monument. Unfortunately, because of a city planning department mistake (they failed to act on paperwork in time) it could not be designated." However, I think the building still exists.
I read somewhere that the oddball values for Philco resistors was owing to the off-color the lights in their factory floor put off. It was therefore necessary to avoid using certain resistor color codes, as certain colors were difficult to ascertain under the factory lighting.
apparently radio-matic made a lot of those coin operated radios. I have a radio-matic coin op radio that fortunately still has the mechanism, but the cabinet is wood. I restored it including the coin mechanism. it gives you 2 hours of "continuous or intermittent reception" for each quarter. you can turn the radio off and the timer stops too, which was nice of them.
Nobody else works on radios this old in this condition. Gotta hand it to Shango because the times I looked at this era chassis I got my butt kicked. Nothing made sense lol.
As I watched the beginning, I realized I had no idea what Bakelite truely was nor how it was manufactured. I searched the youtubesies and found a video named "Bakelite Manufacturing 1936"... Really interesting start to the plastics industries. Thanks for the video leading me down a total rabbit trail.
Beginning of the RCA dominance in USA tubes and circuits patents. This lead to superior cash flow over all its competitors, meaning bigger laboratories, brighter scientists, capacity to take high magnitude risks, etc. They earned a ton of militaria money, as well. Sarnoff leveraged all that to almost monopolize television inventions and early development of its broadcasting platforms. Running NBC and winning the Color Television battle, the 1960s maintained the various cash cows.
Quality decicions in the middle 1960s haunted the early 1970s, especially in the legacy color televisions. Simultaneously dumb expansion decisions drained the coffers.
It's a story of two halves. The fifty years of exceptionalism from early 1920s to early 1970s, where they owned (for better or for worse) the best labs outside of ATT Bell Laboratories and directed the way of consumer electronics to the second half, where the three iconic letters became a thin stick on label.
