Technics SL-P550 (c. 1988–1989)
Not much is documented about the Technics SL-P550. It shows up in period compact disc player directories from the late 1980s as one of Technics' mid-range single-disc players. Hi-Fi-Stereo-Buyers (February 1989, p.105) lists it at $599, with dimensions of roughly 19 × 3.25 × 12 inches. The same directory groups it with the usual late-'80s Technics digital features - quadruple oversampling, a 20-key direct music selector, a 20-selection music calendar, memory backup, and CD-3 (3-inch disc) compatibility. The surviving scan is jumbled, though, so pinning every one of those to the SL-P550 takes some faith.
That is about where the record ends. No production years, circuit details, or owner documentation have turned up in the archive's sources. If you own an SL-P550, or have a brochure that shows where it sat in Technics' late-'80s CD lineup, the archive would be glad to hear from you.
