Denon TU-280G
The TU-280G barely shows up in the record. It's a Japanese-made AM/FM stereo tuner from the early 1990s, and it turns up in classified listings far more often than in any documentation. A single Avito listing dates it to 1993, though no other source corroborates that year. The listings agree on a few things. It was made in Japan, it came in a gold finish, and it was sold into markets where the local FM band differed from Japan's. Nearly every Russian listing mentions the unit being professionally retuned ("перестроен") for the 88-108 MHz range.
The tuner runs on 100 volts, so it needs a step-down transformer outside Japan. It includes a remote control and an original AM antenna. One listing notes the output circuit is low-impedance at 500 ohms, designed to match most amplifiers. Preset memory is 40 stations. The seller on vk.ru states the stereo works and the unit is in excellent condition.
Beyond that, the record is thin. No sensitivity figures, no THD or S/N ratios, no dimensions or weight, no original price, and no professional reviews have surfaced. The few surviving listings are classified ads, not documentation. If you own one and have the manual, it would fill a real gap.
Known specs, such as they are:
- AM/FM stereo tuner, made in Japan
- FM range: 88–108 MHz (after professional retuning for the local band)
- Power supply: 100V
- 40-station preset memory
- Low-impedance output: 500 ohms
- Remote control and AM antenna included
- Production year reportedly 1993 (single source, unconfirmed)
One caution on model naming. Some listings show "TU-280" without the G suffix, and a couple of those carry specs, like 220V power and full Russian FM range reception, that may not apply to the TU-280G specifically. Those are left out here rather than risk attributing the wrong tuner's details.
