PL-P

About the PL-P

The Nagra PL-P is a battery-powered, all-tube preamplifier designed and hand-built in Switzerland, combining classic tube warmth with precision engineering. It features a transformer-coupled moving coil (MC) phono stage with custom hand-wound Nagra transformers, and supports both moving coil and moving magnet cartridges. The unit uses eight high-grade vacuum tubes (including 12AT7 and 12AX7 types) biased for pure class A operation, with precise DC filament voltage regulation for low noise and high resolution. The PL-P is powered by eight rechargeable D-size Nickel-Cadmium cells charged via an external AC/DC converter, isolating the circuitry from mains noise and hum. It includes a Nagra modulometer for accurate level monitoring and adjustment, multiple line-level inputs, a tape loop, and headphone outputs. The chassis is CNC-machined anodized aluminum, measuring 12.2" W x 3" H x 10" D and weighing about 9 lbs 13 oz. The phono stage offers configurable cartridge loading and selectable rumble filters, with internal jumpers for fine adjustments. The PL-P was manufactured from 1997 to 2009 and
