Proton D-1200
Little is documented about the Proton D-1200. The Archive's period sources — dealer price-list ads and test-report scans — contain no listing, review, or specification for this specific model, and no production years or original price have turned up.
What the record does show is that Proton was building high-power amplifiers around the same time. HiFI-Stereo (June 1988, p.65) ran a test report on the closely related Proton D1150 power amplifier, noting half the power of the earlier D/200, a peak rating of 400 watts into 2 ohms, and 6 dB of dynamic headroom. Those figures belong to the D1150, not the D-1200 — offered here only as context. If the D-1200 follows the family naming pattern, it probably sat alongside these models in Proton's late-1980s amplifier lineup, but that is inference.
That is the honest extent of the record. If you own a D-1200, have a period Proton brochure, or have seen it in an old dealer ad, the Archive would welcome the details — feedback link below.
