Carver PM-1.5
Twenty-one pounds that put 450 watts per channel on the road and kept it there.
Overview
The first thing you notice when you pick one up is the weight, or the lack of it. A 21-pound chassis rated at 450 watts per channel into 8 ohms sounds like a typo. For working engineers, that mix of power and portability was the whole point.
The published numbers were conservative. Mix (February 1988, p.39) put a PM-1.5 on the bench and got a clean 480 watts per channel into 8-ohm loads with both channels driven at the rated 0.5% THD. That is above the 450-watt claim. At 20 Hz, the magazine measured 470 watts for rated THD against Carver's published 450. The amp earned a reputation for delivering more than the spec sheet promised.
The design used a low-feedback, high-headroom topology, the "Magnetic Field" branding Carver applied across its professional line. At 21 pounds, you can carry it in one hand to a gig and rack it. Reliability was the other half of the pitch, and the period advertising leaned hard on it - the amp had been "tested and proven" on the road since 1983, per the same Mix coverage.
