The Univox Lafayette U-80A is a Japanese-built amplifier sold under both the Univox and Lafayette brand names in the US market during the mid-1960s, reflecting the common practice of OEM badge engineering by Japanese manufacturers. Its EL34-based power section delivers approximately 40 watts with a bold, aggressive mid-range voice reminiscent of early Marshall designs, and the circuit borrows heavily from British amp topology of the period. The amp is more forceful and compressed than Vox-inspired Univox models, with a harder, more saturated clipping character. The shared-model branding between Univox and Lafayette is documented in collector circles and identifies this as a Matsumoku-affiliated product.
