There used to be a lot of electronics manufacturing in MA. Sad that it has all disappeared overseas and it's all been replaced with Dunkin Donuts, apartments, and office buildings. My grandfather worked at Raytheon back then, and he later moved and worked for AT&T on another manufacturing line, I believe that was in southern NH.

I like the design of that set! I wonder if the reason behind Motorola's offbeat implementation of a lot of the various circuits was to avoid paying a licence fee for some patented design? I can't remember anymore but I seem to recall a lot of early radio circuits had a licence fee on various designs (probably RCA) which led to many creative ways to create a different but similar circuit. Or more likely the bean counters were already hard at work by the 50s and Motorola found they could save some pennies

RCA dominated 1950s television parts and circuits patent control. And into the 1960s in color platform. Solid state components halted that imperial advantage. Ironically, the more televisions became solid state, the more RCA lost both its patent monopoly but its quality as well. They switched to competing on features and price points and made the worst televisions for longevity in late 1960s and 1970s.

It's a weird design and it feels cheap to me, as it places too much reliance on other subsystems. I am not necessarily upset by the use of selenium rectifiers - that would have been high tech in the 1950s and a TV is designed for a 20 year lifespan at best - but.... using the audio output tube as a voltage divider for the vertical? Hard to service even when the set was brand new. You don't go to the audio output tube when you have a vertical issue. I bet this decision cost Motorola a lot in warranty work. Remember that VHS started out as JVC's attempt to build a videocassette which broke Sony's patents. Betamax was better for picture quality than the first VHS machines. But in many ways, VHS proved itself to be superior - recording length, much more open platform allowed more competition, more competition allowed for ,more innovation within the confines of the specifications. And that resulted in VHS HQ and VHS HiFi with the depth multiplexing on the tape. And VHS allowed for more porn, which, as any astute observer of technology will have noted, results in faster adoption - just look at the Internet. Design matters.

Man that looks a LOT like my first television. Dad finally broke down and got me my own TV after I began watching afternoon cartoons in the living room when I got home from school after we moved to town. It was a well used unit looking a LOT like that but with a light that went all around the picture tube. It appeared to be florescent it was that color and you could turn it off if you didn't like it, but I thought it was cool so I always ran it. Had it in my room upstairs so it didn't bother the folks and I could watch what ever I wanted to on NBC as that was the only channel I could get without a good antenna. When I wed and left home, my sister, who lived in a mobile home as a single parent of a young daughter got it because her TV was worse.

Way Back in the early 1970's , I did service calls in the home. I would carry my Huge & Heavy Tube caddy's into the customers living room only to see a set of this vintage WITH a metal case color TV set on top of it . Then a 12" B7W TV on top of that ! 3 sets ! The customer always wanted the color set repaired ( naturally ) and most of the time they also wanted the TV antenna on the roof fixed. It was weird that they kept the 50's TV set as a table to put the newer color TV set on top. Some very good salesman would sell them an alliance tenna rotor for the roof antenna , and almost always the roof top motor was seized and needed to be replaced. ALWAYS when it was freezing cold with ice & snow on the roof. ( I hated that ) . Videos like this bring back a lot of memories , both good & bad ! Thanks Shango.

Mr. Shango, when I was a very young kid my family had almost identical Motorola and I grew up with it, watching Huclkleberry Hound on Friday nights, etc. It was well worn and hard to persuade to tune in a show. The last I saw it run in 1964 the picture tube was so worn out you could only see a picture in totally dark room. In 1970 a friend and I used to junk pick and strip tubes out of TVs. One night I found one of these only older and told my friend I wanted to keep the whole thing. Got it home in my room and found the picture tube totally burned out. The set was in perfect condition otherwise. It was about a 1949 model although it had no date and I had no idea. It was probably one of the first large screen Motorola tvs and had the round flat screen metal cone picture tube. In later years I found a 1950 model ( it had a date ) and it was the same except my 49 had a 6H6 tube , which I believe was a diode tube and the 1950 had just some other diode instead of a whole tube. Another thing I remember about it was the huge transformer sounded almost like a refrigerator motor. The picture tube was burned out and I thought I would never find another weird tube like that but another friend in school said he had a TV for me to play with and it was really ugly hideous thing but I couldn't believe it had just the tube I needed. So I stripped it and at 14 years old with extremely limited electronic knowledge I managed to change the tube out one hot summer day. I actually got it to work and used it for a few years till one day the flyback or something underneath the chassis decided to start arcing real loud like the high voltage start on my tig welder and it scared the hell out of me so I quit running it. It was not a safety set as the whole metal cone of the picture tube was charged with absolutely no covers. I got into cars and girls and eventually tossed it back out. If I had known it went back into the 40s I might have hung on to it longer. It was in brand new cabinet condition. I looked for it online and so far the best I have found is an advertising picture.

This set was a great choice for learning some weird engineering creativity. Love the "Ugmo"! Odd that the Y filament to the damper has one side to ground, and so does the power transformer secondary. I would have thought they would have fully floated that filament like the z winding. Never would have dawned on me that the audio output would have been used as a voltage divider to the other circuits. This video was super entertaining with all the weird squealing, and the camera even picked up the 15.75K high frequency of the horizontal sweep at times. (note: edit changed x to y)

Motorola's gimmick was that bezel and glass called "Glare Guard"! For that era Motorola also boasted "Eighteen Fashion Award Winning Styles". Unknown who gave them that award? It sure wasn't anyone from House Beautiful magazine. In later years they had Drexel furniture manufacturing designed and make cabinets for them. Drexel cabinets were so well done when the set was beyond saving you definitely re-purposed the cabinet because they were really good furniture. As for the electronics, they weren't horrible at all, just different. I've had a few of those over the years and don't remember a lot of issues. Last one was a save that was given no love on powerup. No DBT or nothing , plugged it in and it worked. Ran it for quite a few hours without an issue too. It went on to another collector and is probably still working.
