Luxman T-450 (1976–1980)
The Luxman T-450 is an FM/AM tuner produced from 1976 to 1980, originally priced at 35,000 yen. Almost everything we know about its specifications comes from a single directory entry, so the record is thin. The figures that survive describe a solid mid-1970s analog tuner.
On FM, the T-450 offered a usable sensitivity of 1.8 µV, a signal-to-noise ratio of 70 dB, and total harmonic distortion rated at 0.08%. Selectivity was listed at 70 dB, frequency response from 30 Hz to 15 kHz, and audio output at 0.4 V. The AM section was more modest, with 30 µV sensitivity and 30 dB selectivity. Inside are 14 transistors, 11 diodes, and 2 ICs. It draws 20 W.
Two sources agree on the FM tuning range of 87.5 - 108 MHz. Beyond that, documentation is sparse. No period reviews, no owner impressions, and no service history have surfaced. Dimensions and weight are disputed between sources. One lists 438 x 148 x 372 mm at 7.8 kg, while another gives 400 x 144 x 303 mm at 8.5 kg. Without a manufacturer manual to settle it, both sets of figures should be treated with caution.
