Pioneer TX-9100 Tuner

Here we have a vintage tuner from Japanese company Pioneer. Originally launched way back in 1974 ours is in good fully working condition and is showing only very light signs of its age. Amazingly it comes in original factory packaging, and with our usual three month warranty.
Pioneer Said….
Pioneer’s finest tuner is a rich stereo achievement that offers one of the finest FM sensitivity ratings ever built-in to a tuner. Among its many quality features are a 5-gang variable capacitor and low-noise dual-gate MOS-type FETs employed in the FM front end, resulting in a superb 1.5 µV (IHF) sensitivity figure, spurious rejection of more than 110 dB and image rejection of more than 110 dB. For outstanding selectivity, Pioneer has used phase-linear ceramic filters in the IF section, coupled with a 6-stage limiter by monolithic ICs with differential amplifiers. Such sophisticated circuitry results in a 90 dB (IHF) selectivity characteristic, plus improved phase characteristics and a signal-to-noise ratio of 75 dB. Capture ratio is equally superb, measured at 1 dB (IHF). The multiplex circuit in the TX-9100 consists of the Phase-Lock-Loop circuit, a prime reason for the tuner’s low-distortion and wide separation, as well as its reliability and stability. Other features include a sharp low-pass filter that cancels carrier leaks, a twostep FM muting switch, a double-action FM muting with reed relay to cancel irritating inter-station noise, plus a pulse noise suppressor. Even the AM tuner section is advanced, consisting of a frequency-linear AM 3-gang variable capacitor coupled with one-stage RF amplifier to provide quality AM reception
