Product description This super servo integral type stereo power amplifier analyzes the amplifier not only as a single electric circuit, but also includes the acoustic aspects of the reproduced sound field, and thoroughly investigates the problem of time difference distortion. In addition to Onkyos proprietary W Super Servo method, it also uses a Super Servo Integral method that suppresses the effects of the speakers electromotive force. When the voice coil of a speaker vibrates, a microphone effect occurs in which an electromotive force is generated within the coil, which affects the reproduced sound. The super servo integral system employs a circuit that reduces the influence of this electromotive force to -20dB or less, and applies positive and negative feedback using a linearity correction circuit only to the current amplification stage to improve the linearity of this stage. This has dramatically improved and suppressed time difference distortion.The final transistor operates using a linear switching method.This method uses two transistors for amplification, similar to class B operation, and uses a special bias circuit to correct the linearity of the joints of the operating curves, which is a problem in this case, to obtain linear operating characteristics. Masu. As a result, crossover distortion is reduced, and characteristics close to class A operation are obtained while retaining the benefits of class B.Furthermore, by using a High fT power transistor, switching distortion is suppressed to a negligible range.Logarithmic compression and peak hold are performed using a highly stable monolithic IC, and it is equipped with a large peak meter that suppresses left and right variations.In order to obtain high-speed response, it is driven by a dedicated meter drive circuit using an operational amplifier, and the level can be changed from 0dB to 130W and 13W with the front switch.A monolithic IC is used for the protection circuit, which not only improves stability, but also detects DC leakage voltage appearing at the speaker terminals and overcurrent in the power stage, and in the unlikely event of an emergency, the relay will be shut off to protect the circuit components. . A highly reliable gold-plated silver contact relay is used for the speaker switching relay, and the use of a parallel connection prevents deterioration of the damping factor.In addition, the low-pass filters for DC voltage detection are independent on the left and right, and work even when the left and right polarities are different.The power supply section uses a large twin-wide type power transformer, and the rectifying chemical controller is a low-inductance circuit that is a multi-tab type low impedance wide range chemical controller that is directly connected to the bus earth after careful consideration. I am using it as.In addition, the power supply and distribution to each section, the ground line, etc. are also thoroughly low impedance.It uses an auto-tracking bias method that detects local temperature changes in each part and provides a stable bias supply.?Main specificationsModel W/Super servo stereo power amplifierEffective output (20Hz-20kHz) 170W+170W(4?)130W+130W(8?)Dynamic power (1kHz) 200W+200W (8?)Total harmonic distortion (THD, 20Hz to 20kHz) 0.003% or less (at effective output) 0.002% or less (at 65W output)Cross-modulation distortion (SMPTE 70Hz:7kHz=4:1) 0.003% or less (at effective output)Power band width (IHF -3dB, THD 0.2%) 5Hz to 100kHzGain 30dBFrequency characteristics 1Hz to 100kHz +0 -1.5dBSN ratio (IHF-A network input shunt) 120dBInput sensitivity/impedance 1V/47k?

This auction is for a vintage Onkyo Integra A-8067 Integrated Stereo Amplifier with Servo Operation. I believe that it was manufactured in 1985. This unit is in good condition, just minor surface scratches and blemishes that could be touched up. I have tested every input, including the phono stage, and the only thing I could not test is the Moving Coil option for the turntable cartridge because all of my turntables have either Moving Magnet or Moving Iron cartridges. All of the outputs on the amplifier work (speaker outs and both tape outs). This amplifier sounds and operates great. I’ve included a video to show it playing and to show some of the knobs and switches in action. Because of my limited space for taking photos and videos, the speakers I used for the video are just small Yamaha bookshelf models, but they are 6 ohm with a fairly high power rating for their size (my phones mic doesnt do their sound justice). The speakers are NOT included in this sale. Here are the amps specs (I found them online on HiFi Engine, but I believe they are accurate): Power output: 80 watts per channel into 8? (stereo)Frequency response: 2Hz to 50kHzTotal harmonic distortion: 0.015%Damping factor: 50Input sensitivity: 0.16mV (MC), 2.5mV (MM), 150mV (line)Signal to noise ratio: 72dB (MC), 80dB (MM), 84dB (line)Output: 150mV (line)Semiconductors: 5 x IC, 42 x transistors, 46 x diodesDimensions: 435 x 144 x 391mmWeight: 12kg Shipping costs will be calculated based on the buyer’s location. This unit will ship by UPS. It weighs 25 pounds. I do heavy-duty packing and estimate that the box and padding material will add an additional 5 pounds to the shipping weight, and I estimate that the shipping box will measure approximately 24x24x18 inches. The package will be insured through UPS. The pics here are of the actual item for sale (not stock or snagged pics). As always, I will make sure that all my sales are handled as professionally and pleasantly as possible. Ill answer any questions I can. If you require move photos or videos, just let me know. Thanks for looking! Please see my other auctions as I am selling an Onkyo Integra T-4057 AM-FM Tuner, which is a great match for this amp. I am also selling an Onkyo EQ-25 Graphic Equalizer thats also a great match. I always do my best to offer fair combined shipping. (If buying more than one of my items, dont pay until I adjust the invoice.)

This pre-amp is in excellent condition and sounds awesome. I am only selling because of downsizing at this point in my life.I am an electronics tech of many years, so rest assured this item has been taken care of. The bulbs and rubber lenses have been replaced with new ones. The originals in these are usually burnt up so bad they crumble at first touch (see photo 7 and 8 for removed ones). I found some new old stock ones with new lamps! the display looks nice and bright.See the photos for before and after shots. also, this piece is very easy to work on if every needed.these are built like a tank. cosmetically it looks great, there is a ding on the top left wood panel front, however its not a bad one if you zoom in on the first photo.
