Marantz PM-15

Name: Marantz PM-15
Brand: Marantz

The Marantz PM-15 is a stereo integrated amplifier from the company's Reference Series. It's a dual-mono design with a "Current Feedback" circuit topology. Marantz fitted it with an oversized power transformer and high-capacity filter capacitors, the kind of premium parts that defined the Reference Series approach. It's a big unit at 440mm wide, 370mm deep and 120mm tall, and it weighs 13.5 kg.

The PM-15 is rated at 100 watts per channel into 8 ohms (RMS) and 180 watts per channel into 4 ohms. Frequency response is 5Hz - 100kHz, total harmonic distortion is 0.005%, and signal-to-noise ratio is 100dB. Inputs are phono (both MM and MC), CD, tuner, aux, and two tape loops. On the output side there's a pre-out, tape outputs, and a headphone jack.

The record on this model is thin beyond the basics. No production years are documented, no original price has surfaced, and no owner reviews or technician reports have been captured. The magazine chunks in the archive are fragmentary. A 1962 issue of Audio (July 1962, p.56) carries unrelated classified text, and a 1997 issue of Sound on Sound UK (1997, p.260) contains only a small-ads page. No period review of the PM-15 has been preserved in the research. The sources do agree on the hardware: the dual-mono construction, the current feedback topology, and the generous power supply.
