Harman Kardon 230A It is incredible how a so old amplifier sounds. I have bought 54 year Harman Kardon 230A perfect conditions all original. Wonderful. Very very pleasant sound. Inside all components are in a particular order that confirm the good project. There are no noise or buzz or hiss. I love it! It is connected to a T+A PP120 speakers. Listening Jazz is pure melody. The bass are present with deep sound and body but are not intrusive, they are really balanced. Voices are present and the treble are not so metallic like modern amplifier. It is a masterpiece. General: Manufacturer: Harman/Kardon Model: 230A Type: Receiver Years of manufacture: 1972 - 1974 Made in: USA Beware: Reserve Price – This opens at €450,00 – Below that price you cannot buy this. Identical to the Harman Kardon 230 (Nocturne era) other than cosmetics • In the “minimalist” mostly-silver with black edges case like the 330A and 330B • Has separate AM and FM tuning panels (but they share the tuning knob) • Does NOT have pre-out / main-in jacks • From harman-kardon-230A : o The Harman-Kardon engineering team has completed a high performance stereo receiver which exceeds every specification ever established for medium priced stereo components. The new Model 230A combines the finest stereophonic sound with the industry's most distinctive styling to give high fidelity a new standard of excellence and performance at a price of less than $160.00. o Tuber sensitivity of the 230A is extraordinary. It pulls in distant stations without noise or fading. AM and FM performance neve deteriorates with age because the receiver produces no heat to change the value of component parts. o And when you tune the 230A to a station, it locks into place and never drifts. o The 230A adheres to the same philosophy of design that makes all Harman-Kardon receivers sound more transparent and lifelike. Frequency response, which is usually limited to the narrow range of 20-20,000 Hz in most receivers, is extended well beyond those parameters to give the sound you hear greater clarity and definition. All of the subtle nuances and shadings of music emerge with exciting realism. • Published specs o Power Output: 17 watts into 8 Ω, 20 watts into 4 Ω o Total Harmonic Distortion: less than 1% o Frequency Response : 20 Hz to 20,000 Hz o Power Bandwidth: 15 Hz to 70,000 Hz (at less than 0.3% THD into 8 Ω, both channels driven simultaneously at 8.5 watts per channel) o Frequency Bandwidth: 7 Hz to beyond 130 kHz o Frequency Response: 15 Hz to 70,000 Hz ±1.5 dB o Power Supply: AC, 110 - 240 Volt o Dimensions: 390 x 100 x 190 mm (15.4" x 3.9" x 7.5") o Weight: 6,5 (14 lbs 15,1 oz) • Features o From HK literature:  No deterioration with age because there's no damaging heat. You can expect the same high quality performance from 230A even after years of extensive use.  A special electronic circuit automatically switches FM tuner to stereo, the moment a stereo broadcasts received. Special light indicates FM stereo reception. Receiver switches to standard FM automatically when stereo broadcast ends.  High speaker damping controls excessive speaker excursions to avoid distortion during sharp bursts of sound. This results in clean, tight bass.  Contour for low-volume listening maintains full bass response even at levels where bass normally falls off.  Precise D'Arson val movement tuning mater shows when you have tuned to strongest and clearest signal on AM and FM  Stereo in two rooms. Simple front panel switching eliminates the complexity and expense of external switching devices. Headphone receptacle permits personal listening.  Newly designed dial illumination shows AM or FM dial scale independently for maximum visibility.  Entire top section of receiver turns black when receiver is switched to phono mode of operation.  Illuminated push-button ON/OFF switch glows in red to indicate that receiver is on.  Continuously variable balance control lets you adjust stereo balance to suit acoustic requirements of your room. Permits you to sit far to one side of your room and still maintain perfect stereo.  Tape Monitor Switch for instant comparison of recorded material and original program.  Extended frequency response beyond the normal hearing range gives extra realism to the sounds you can hear. 230A sound is cleaner, more transparent, more sharply defined. You can actually feel the difference.  Separate illuminated power On/Off switch permits you to turn receiver on and off without upsetting other controls.  Heavy, counter weighted flywheel makes tuning smooth as silk.
