The age of this compact SA-36A generation matters less than its simplicity: it remains a useful little Class D amplifier rather than an obsolete curiosity. At £22, it is a strong bargain, sitting well below the £50 25th-percentile figure from 267 comparable listings and far under the £94 median.
Its appeal is straightforward: small, efficient, clean-sounding amplification with enough grip for efficient bookshelf speakers, desktop systems, or a secondary room. The missing power supply is the one material catch, but at this price it still looks like a worthwhile buy if the amplifier is tested and the seller confirms the correct voltage and polarity. Budget for a compatible supply, check that both channels work quietly, and you could have an excellent low-cost system-building component.
