Bell

The brand name Bell was more well known for its range of television sets and radios but they also did venture into making audio products during the 1970's. 

Unfortunately Bell earned a reputation for their colour televisions not being terribly great or reliable and this cast a shadow over the brand in its later years. 

The black and white televisions were far better and Bell was one of the first to manufacture sets and were responsible for the some of the earliest TV broadcasts.

At this stage it is not clear what the range or production run of Bell stereo equipment was made. They also used the name Majestic which was more focused on the audio range.
