[5] [6] The lower cost of transformerless designs remained popular with manufacturers long after DC power distribution had disappeared. Several models were produced which dispensed with the power transformer, but ...
A 5-tube superheterodyne receiver manufactured by Toshiba circa 1955 Superheterodyne transistor radio circuit circa 1975. A superheterodyne receiver, often shortened to superhet, is a type of radio receiver that uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original carrier frequency.
