Quad 15

Little is documented about the Quad 15. No distinct model by that name appears in the available period literature or specification sheets. The number "15" shows up only as a power rating - 15 watts per channel - tied to the Quad II amplifier, which Audio-Collection (1964, p.10) notes delivers 15 watts across the 20-20,000 Hz range. Most likely "Quad 15" is a misattribution, or a loose way of referring to the Quad II's output, and not a separate product. No period advertisements, service manuals or official documentation name a Quad 15 as its own model. If any reader has original materials showing a Quad 15 as a distinct product, the Archive welcomes correction.

• Type: Unknown — no verified identity found
• Production years: Not documented
• Specifications: None recorded for this model name
• Likely origin: Confusion with Quad II amplifier (15 W/ch)
