The Harman Kardon 330B was a modest offering from the company. It was designed as a budget receiver that still produced hi-fi level sound. It produces 18 watts per channel so if you want to shake your foundation then it’s probably not for you. However, for a low end, budget minded receiver it produces some really nice sound and sold for only $199 when introduced.
The 330B was introduced around 1973, followed by the 330C, and was somewhat of a staple for many years. You’ll find many people who still own and rave about their 330B and many others who regret selling their 330B. That should tell you something about their performance. They are very minimalist in their design. A simple red power button, black switches, and corrugated knobs run across the front. The tuning knob is only slightly larger than the other knobs. The split front panel with brushed aluminum bottom and black glass top give it a different look. An optional walnut cabinet was also available.
The 330B is a really well built receiver for it price. It weighs about 21 pounds and measures 15 3/8″ W x 13″ D x 4 1/2″ H.
While many audio manufacturers of the time insisted that the human ear couldn’t hear below 20 Hz and above 20 kHz Harman Kardon felt differently. They specifically designed their amplifier circuitry to reproduce frequencies well below and above these alleged limitations.
The Harman Kardon 330B was manufactured as a lower end budget receiver and most stereos of that type don’t sell for much these days. But, the 330b holds its own.
