This is a harman/kardon 330c and it is downright gorgeous and in EXCELLENT condition--electronically and cosmetically--it looks like it was manufactured yesterday. All the hallmarks of early-70's h/k gear is here: black glass plate with green dial and illuminated, translucent red power button. This could be the centerpiece of a killer vintage Hi-Fi setup, especially paired with some equally beautiful speakers. The harman/kardon 330c is the final and most refined iteration of the acclaimed 330 series, produced between 1976 and 1978. Though conservatively rated at 20 watts per channel, it is widely praised for its "warm," tube-like tone and exceptional headroom, often sounding much more powerful than its specs suggest.Tuning range: AM/FMPower output: 20 watts per channel into 8Ω (stereo)Frequency response: 20Hz to 20kHzTotal harmonic distortion: 0.5%Damping factor: 30Input sensitivity: 2.8mV (MM), 200mV (line)Signal to noise ratio: 75dB (MM), 85dB (line)Dimensions: 16" x 12" x 5"Weight: 20 poundsService History: No service records were included from the prior owner.

Harman Kardon traces its origins to 1953, when Dr. Sidney Harman and Bernard Kardon, both engineers frustrated with conservative audio manufacturing at the David Bogen Company, invested $5,000 each to launch their venture in Westbury, New York. Their debut product, the Festival D1000, became the world's first compact AM/FM hi-fi receiver, blending breakthrough technology with sleek design to make high-fidelity sound accessible beyond technical enthusiasts. Pioneering innovations like the 1958 Festival TA230 stereo receiver, the 1959 Citation II ultra-wide bandwidth tube amplifier, and the 1970 CAD5 hi-fi cassette recorder with Dolby noise reduction cemented their legacy in simplifying premium audio for the home.
The brand focuses on integrated receivers, amplifiers, tuners, and speakers that emphasize performance, reliability, and elegant industrial design. Over decades, it expanded into home theater systems and automotive audio, powering systems in vehicles from Land Rover and BMW to Volvo and Polestar. While not delving into turntables, DACs, headphones, or cables, Harman Kardon prioritizes cohesive hi-fi components that deliver warm, detailed sound without unnecessary complexity.
Harman Kardon holds a solid mid-tier position in the hi-fi market, renowned among knowledgeable buyers for its enduring quality and value rather than ultra-high-end exotica or vintage collector status. Now part of Harman International, it appeals to discerning listeners seeking dependable, stylish gear that echoes its innovative heritage without commanding boutique premiums.
