Advent 300 Stereo Receiver (1976)
Advent 300 Stereo Receiver was known for a few things. It had a very good FM stereo tuner, a well regarded headphone output, and an excellent phono stage preamplifier. The electronics were partly designed by Tomlinson Holman, later of APT and THX fame.
The receiver came in silver and black, but more interestingly, also came as a 12volt model for use in cars and recreational vehicles.
