Sanyo P-55 (Circa 1979–1981)
The Sanyo P-55 is a power amplifier from Sanyo's separates line of the late 1970s and early 1980s. The record is thin but specific. High Fidelity (1981, p.212) listed the P55 as a 60-watt (17.75 dBW) continuous power amplifier at $449.95. It measured 3½ × 17⅜ × 10⅝ inches (H × W × D) and weighed 26 pounds net. The same listing paired it with Sanyo's CA-F1 preamplifier, which cost $495.
The P-55 was on the market earlier than that. Audio (October 1979, p.49) ran it in a component listing alongside the Phase Linear 300 Series Two and a Threshold amplifier, which suggests Sanyo was aiming it at the serious-separates crowd rather than its mass-market receiver buyer. Nothing else has surfaced beyond those two appearances. No service manual, owner reviews or production dates are documented in the available sources.
