Here is the first B-T UHF converter housed in
a plastic cabinet. It was used to enable TV sets of its time to receive
the then new UHF TV stations broadcasting on channels 14-83. Various
tubed and solid state B-T UHF converters for home use were in continuous
production from 1952 through about 1980. |
Here is the "Audio Baton". It was the

invented and patented by Ben H. Tongue. Production was from about
1959 through 1961. |
