BSR Quanta 400 (1978)
Not much is documented about the BSR Quanta 400. The record is one trade notice from May 1978, which announced it as a new belt-drive automatic single-play turntable from BSR, priced at $79.95. HI-Fi-Stereo-Buyers (May 1978, p.40) noted it came with an S-shaped tonearm and a pre-fitted ADC QLM pickup. No further specifications - motor type, speeds, wow and flutter, dimensions - appear to survive in any known period source. The same announcement listed it alongside Marantz's top-of-the-line 6350Q and Kenwood's KD-750, but at a fraction of their prices, which suggests a mass-market target, not a high-end one. Beyond that listing, no reviews, user manuals, or service documentation have turned up.
