Pioneer SA - 9900 TX - 9800 Stereo Integrated Amplifier And Stereo Tuner Set

Pioneer SA-9900 StereoIntegrated AmplifierPioneer TX-9800 AM/FMStereo TunerVery nice Pioneer SA-9900 Stereo Integrated Amplifier and PioneerTX-9800 AM/FM Stereo Tuner set. All inputs/outputs, switches, meters, and lightshave been thoroughly tested and are working perfectly.They work and sound great. The SA-9900 wood case is perfect. TheTX-9800 I only just picked up to complement the set. (I was using a differenttuner.) The TX-9800 case has some blemishes on top. Please take a close loo...k atthe pictures. I have taken pictures with and without the flash for addeddetail. A copy of the Operating Instructions and a SA-9900 color brochure willbe included.This will be double-box packed and shipped by UPS.(I am downsizing and, sadly, selling some of my high-endequipment) * Output tested with (2) Bose 901 series VIspeakers* Tape Inputs - Tested with “Akai Surround Sound Demonstration Tape”played on a Sansui QD-5500 tape deck. PioneerSA-9900 Stereo IntegratedAmplifierDescription (fromthevintageknob.org):The SA-9900 is a top of the line stereo integrated amplifier withstate-of-the-art technology and advanced features.Differential amplifier circuits are employed in the equalizer, tone control and power amplifier sections.Each amplifier section is supplied by a balanced power supplysystem that assures excellent DC balance and stability, while nearlyeliminating switching noise during control operation.(From thevintageknob.org)” Yes : they still do make 'em that big and heavy. Just not ashealthy, that's all.If the next gen' would see a major improvement in specs (SA-9800), the SA-9900 was as lavish an integrated amplifier as the mid-1970s couldproduce, with an internal structure closely related to the SPEC series and theEXCLUSIVE C3 preamplifier.Differential FET- and PNP/NPN-charged phono section, differentialFET- and PNP/NPN-charged stepped tone controls, 2-gang volume control, biiiiiigtrafo, two 22, 000uF caps, large heatsinks cooling four pairs of 12A / 100Wbipolars.Plus a physical structure which many (most) would rapidly followbefore the use of relays made internal layouts simpler for everybody : sourcei/o's to the right side, outputs to the left side - straight and simple.Looks-wise, it is safe to say that the SA-9900 set the tone forPioneer's golden age, before the interesting, often magnificent if shortliveddesign attempts of the very late 1970s and early 1980s : solid stack of shinysilver with nothing else but... shiny silver !The big volume pot is lit from its surrounds but it is somethingthe 1970s photographers (and Pioneer's publicity teams) forgot to capture onfilm most of the time - silly.But unlike most of the early 1980s efforts, the SA-9900 stillshines, today.”Specifications:Power output: 110 watts per channel into 8Ω (stereo)Frequency response: 7Hz to 40kHzTotal harmonic distortion: 0.05%Damping factor: 30Input sensitivity: 6mV (mic), 2.5mV (MM), 150mV (line)Signal to noise ratio: 65dB (mic), 70dB (MM), 95dB (line)Output: 150mV (line), 2V (Pre out)Speaker load impedance: 4Ω to 16ΩSemiconductors: 10 x FET, 74 x transistors, 33 x diodes PioneerTX-9800 AM/FM Stereo TunerDescription (fromclassichifi.info):The TX-9800 RF amplifier 2-stage front end incorporates a 5-gangvariable capacitor and three dual gate MOS FETS.A capacitance controlled double tuned circuit is inserted betweenthe RF amplifier stages.Those features produce impressive characteristics such as an IHFsensitivity of 8.8dBf, a spurious response of over 110dB and an imageinterference ratio of over 120dB.(From classichifi.info):“The TX-9800 was at the very top of Pioneer's range of tuners in1979 was the last of their great analogue AM/FM tuners. As was the norm forhigh-end Japanese in the 1970's, the build quality is excellent with a verythick aluminum front panel, milled aluminum controls, super smooth flywheelassisted knob and a very solid build generally. The TX-9800 was beautiful tolook at and a delight to use with sound quality that would knock spots off anymodern FM or DAB tuner. It was the first Pioneer tuner to feature the use of a quartzoscillator to eliminate drift on FM. The large tuning knob had a touchsensitive system that switched out the quartz lock when being tuned - veryclever! After tuning to the center of the desired station by getting the tuningmeter to be in the center and the Center Tune LED to illuminate, the quartzlock would activate when you let go of the tuning knob. The green "QuartzLocked" LED would then light up and the station would be"locked".”Specifications:Type: Mono/Stereo TunerTuning Bands: FM, MWTuning Scale: AnalogueSensitivity: 1.5uV (FM), 300uV (MW)Signal to Noise Ratio: 80dB (FM), 55dB (MW)Distortion: 0.2% (FM)Selectivity: 85dB (FM), 50dB (MW)Frequency response: 20Hz to 15kHz (FM)Output: 650mV (FM), 200mV (MW)Semiconductors: 11 x IC, 11 x FET, 30 x transistors, 48 x diodes
