Sansui D-33 (Year unconfirmed)
Not much information survives on the Sansui D-33, and even the exact model name is uncertain. The Archive has found no fact sheet, service manual, or catalog listing for a component called precisely “D-33.” The one period reference that appears to belong to this model is a review of the AU-D33. That name suggests the same unit may have been sold with or without the “AU-” prefix, depending on the market.
Audio-Collection (p.112) described the AU-D33 as a lower-priced application of Sansui's “Super Feedforward” error-correction circuitry, the same technology used in the 100W AU-D9. The review rated the AU-D33 at 50 watts per channel and listed it at a “modest” £140. It praised the all-black finish and balanced front-panel layout, and noted it was a genuine Made-in-Japan product.
If the D-33 is indeed the AU-D33, it was an integrated amplifier from the early 1980s, positioned below the AU-D9 in Sansui's lineup. Nothing else is documented. No production years, no US pricing and no further specifications have surfaced in the period record.
