Technics SU-7700 Integrated Amplifier Transistor Premain Junk Not Working japan Description Condition: used This is the Stereo Integrated Amplifier SU-7700 released by Technics around 1976. It can be used, but there is a problem with the sound output, so I am listing it as a junk item. ?Appearance: The interior and exterior of the case have been carefully cleaned, so there are no noticeable scratches or stains and it is in good condition. ?Sound output: We connected a record player, FM tuner, CD player, and two cassette decks to the input terminals (phono, tuner, aux) and tape play and rec terminals on the side panel, and checked the sound through the speakers and headphones, and found the following problems.? When the speaker is connected to main, no sound is produced from the right side, so by connecting it to remote, sound can be produced from the left and right.? You wont notice it when listening to music, but you can feel noise when you turn up the volume with no sound (no input).? When the volume is low, the sound on the left side may be interrupted, but this will be resolved over time. ?Operation: The output meter lights up and the needle swings have been confirmed. When switching the meter range (x1, x0.1) to x0.1, the needle swings widely, which is thought to be normal.The power, speakers, high filter, loudness mode, rec mode, tape monitor, input selector, and EQ subsonic switches all function normally.The bass, treble, and balance adjustments all function without any scratching, but the volume is as explained in ?. *The above confirmation method is audiovisual. ?As this is an old product, please be aware that malfunctions may occur due to vibrations during transportation and deterioration over time. Please check the appearance in the photos before purchasing if you are satisfied with the condition. Payment Please pay within 5 days after the auction closed.

There are large scratches and dirt that anyone can see.Fully operational and functions (D)- Overall condition is bad. There are troubles such as troubles during use, defects, and large dirt. Junk etc. If you have any questions, Please feel free to contact us This pre-main amplifier uses a side terminal structure to achieve a straight circuit configuration. The terminals are directly connected to the printed circuit board without wires, allowing input signals to be input straight into the circuit.The side terminal layout also enables straight transmission. The equalizer circuit uses an IC configuration. The circuit configuration uses differential amplification with a current mirror load as the first stage, and an emitter follower with a constant-current load as the output stage.The large gain of the first stage reduces the noise level.In order to obtain accurate frequency response, a metal film resistor with ±1% deviation and a polypropylene capacitor with ±2% deviation are used for the equalizer element. The first stage of the main amplifier section consists of a differential amplifier using a pair of transistors in a single package and operates with a current mirror load. High gain with low distortion is obtained in the first stage, which is attacked by negative feedback using NF technology.For the power transistors, large-capacity transistors are used in a complementary manner to achieve low distortion and low noise. A protection and muting circuit using relays is provided to suppress noise when the power supply is turned on and off. The power supply section uses a newly developed high-density transformer with high-density coils wound in a small space by using sophisticated winding technology. This allows for a large volume-to-weight ratio, resulting in a high output power with high efficiency. It also features excellent regulation and low leakage flux. A 10,000 ?F electrolytic capacitor is used for the capacitor.For the preamplifier section, a ±2-supply constant voltage power supply with transistors and Zener diodes is used. In addition, the common emitter power supply for the first-stage differential amplifier of the main amplifier is supplied with a constant voltage using Zener diodes to enable stable amplification. A subsonic filter is provided using the NF loop of the equalizer circuit. The tape monitor and recording mode selectors are independently configured so that other sources can be played back while dubbing. The volume is a 41-point step type. A newly developed volume is used for the tone control, and the circuit is disconnected from the signal circuit at the knobs midpoint. In this position, the signal circuit is limited to the equalizer amplifier and power amplifier, resulting in an extremely simple circuit configuration.The tone control circuit uses the NF circuit of the main amplifier. A high filter is provided. A germanium diode is used for rectification, and a direct-reading output power meter is provided for improved linearity at low output.PaymentWe accept Payoneer / Paypal / Credit card.*According to regulations, VAT (Value Added Tax) will be added to the price of goods for orders from the UK or EU.Please contact eBay for details.ShippingShipping from Japan with Tracking Number & Insurance.For handling time, please refer to the Shipping and Payments section.
