Vintage Sansui TU-9900 AM/FM Stereo Radio Tuner Retro Antenna BlackThis product data sheet is originally written in English.DescriptionWe have 100% stock & Ready to ship!!All accessories are as pictured.Although it is now a product of Sansuis prosperous days, it is the Sansui AM FM tuner TU-9900 in good condition . Both sensitivity and playback sound are good. The operation of the meter and each switch is also confirmed without problems.Below is an excerpt from the audio footprint. Please referAn FM/AM tuner that thoroughly pursues reception performance as a tuner in order to perform stable reception in all radio wave conditions, and that incorporates excellent circuit technology and carefully selected materials in order to achieve both audio performance at the same time.A frequency linear type FM5-series variable condenser, three low-noise dual-gate MOS FETs, and one transistor are used for the front end part. Furthermore, the antenna attenuator switch is also carried, and the stable reception is enabled also in the short distance of a long-distance reception area and a strong electric field.The IF part is equipped with reception band switching, and both sound quality emphasis and reception performance emphasis are achieved.Two steps of 6-pole block filters with flat group delay characteristics are used for the broadband, which emphasizes sound quality, and a narrow-band 4-pole ceramic filter is used for reception with excellent adjacent interference elimination capability for the narrowband.The differential demodulation circuit and the PLL (phase lock loop) system excellent in the phase characteristic are adopted as the ultra-wideband ratio detection circuit and the MPX section. Linearity is good over a wide band by this, and the low distortion equivalent to an integrated amplifier is enabled.Equipped with an auto noise canceller that employs a photocoupler, when a weak signal is input, the amount of blending to the left and right is automatically changed according to the signal level to cancel noise. As a result, practical performance on hearing is improved.In the AM tuner part, a double-tuned circuit, a YA-MAN type ceramic filter with two elements and two coils, etc. are adopted for improvement in sound quality and selectivity.The stable power supply by ±2 power supply with good regulation is adopted as each block stage, and the stable operation and sound quality improvement are aimed at.The test oscillator for recording which can perform the appropriate level setting in a deck easily is built in.The signal is 1 kHz, and the level of -10 dB at 100% FM modulation is obtained. In addition, this signal sound can be used to check the speaker phase and adjust the left/right balance.A low-pass filter with sharp characteristics is installed to avoid beats with the deck.The output-terminal only for sound recording is carried.The signal meter and the center tuning meter are adopted.A flexible type AM bar antenna, a multipath observation terminal, an FM detection output terminal, a 75?F type FM antenna terminal, and an output level adjustment function are carried.It uses a heavyweight sintered alloy flywheel and a glass dial surface that does not change over time.Please check the condition with the photo and video.PaymentVarious credit cards, Apple pay, Google Pay etc.ShippingWe ship by DHL or Fedex.
