The Pioneer F-737 is a tuner that was manufactured in Japan between 1988 and 1989. It features a sleek design available in silver and black finishes. With dimensions of 420 x 86 x 316 mm and a weight of 4.1 kg, it has a modest footprint that fits well in various audio setups. The unit has a power consumption rating of 10 W and offers a range of technical features aimed at enhancing audio output and reception quality. It has a frequency response of 20 Hz to 15 kHz for FM signals and provides outputs of 650 mV (FM) and 150 mV (MW). The tuner is equipped with a digital synthesizer and a digital direct decoder, which enable high sensitivity and stable reception. This is facilitated by an input stage with a Pioneer ID MOS FET (P001) and a balanced mixer stage that minimizes RF intermodulation distortion. The detector utilizes a phase-locked loop (PLL) for improved impurity spacing. The design incorporates a honeycomb-reinforced chassis and a resin-filled oscillator module, aimed at damping impact noise for better sound quality. User-friendly features include fixed station presets for 24 FM/MW stations, timer preset capability for recording, a switchable muting threshold, and adjustable bandwidth options for clarity in reception. The clear fluorescent display enhances usability, and a test tone generator assists in measuring recording levels.
