Nagra PL-P [Expired]


no longer for sale


I know I'm going to regret this, but here we go:  
I'm selling my beloved Nagra PL-P, the finest phono preamp I have ever owned or heard. I dismantled most of my system after my child was born, but kept this and a Schroeder Reference arm to build a future system around. But the kid isn't getting any cheaper...
Battery operated tube phono preamp with adjustable loading for your cartridge (currently set for an Allaerts MC-1b). There's a little set of timers inside the preamp that tell you when you should replace the tubes: these show lots of time left on the current brace of Nagra tubes, but   I'm also including a brand-new, unopened Tube Kit for the PL-P, an $840 value. Nagra doesn't make the original style battery sleeves any more, so at the recommendation of Rene Laflamme, the Nagra North America rep, I've been using Energizer NiMH 2500 mAh D-size. These are an improvement, as they don't have a "memory" like the originals.

Here's what Nagra has to say:
KEY FEATURES
UNCOMPROMISED POWER SUPPLY

In any pre-amplifier, the power supply is a sensitive and significant component. This is especially true when dealing with phono levels. That’s why the PL-P power supply uses a set of rechargeable “D” cell batteries, operating through an external current charging AC supply. This design eliminates all disruptive effects of AC powering from wall outlets and may solve persistent hum problems. The internal power supply regulation circuitry of the PL-P uses proprietary, dual DC-to-DC converters to eliminate power supply ripples and assures a clean power source for all active electronic stages and components.

UNIQUE DESIGN PHONO STAGE

The phono stage is built around the best tubes out of our selection and especially designed Nagra transformers for impressive noise figures, dynamic and high-resolution performance with both moving magnet and moving-coil cartridges.

Variable capacitive (from 47 pF to 837 pF) and resistive (30 Ω to 330 Ω) loading is provided to allow ideal matching with most available cartridges. Switches for selecting the appropriate loading options are internally mounted on the circuit board to protect sensitive low-level signals from undesirable interferences.

A-CLASS TUBE

Two triode sections, biased for pure class-A operation, are implemented in each channel for additional amplification. The PL-P has two stages, the first one for level input management and the second for output level management and record loop.

As in all vacuum tube circuits within the PL-P, precise DC filament voltage regulation from the power supply ensures low-noise, high-resolution performance and a long lifetime. The output stage vacuum tubes, operating in pure class-A, are directly coupled to the output connectors; they can accommodate loads as low as 600 Ω. To facilitate tape transcriptions and external signal processing, a full tape loop facility is also provided.

ERGONOMICS

Input selection is made on the left side of the front panel using a precision rotary switch. One phono and three line level inputs are provided. Input levels for all sources can be adjusted via left and right potentiometers on the front panel. A clever geared clutch mechanism, allows these channel adjustments to be made either independently or together.

ATTENTION TO DETAIL

To reduce unwanted interference, the main circuit board is mounted on elastomer dampers to eliminate the effect of external vibrations.

To conserve component life and battery reserve, only those vacuum tubes required for the selected input are turned on. The audio output is automatically muted when switching between input sources.

TRADITION – LEVEL MATCHING THROUGH THE NAGRA MODULOMETER

A highly precise, Nagra-made modulometer, identical to the legendary NAGRA IV-S, provides a multitude of functions through two coaxial, internal pointers representing the left and right channels. The Nagra modulometer is a true measurement device that allows precision over a large scale. The modulometer can be used to adjust the volume and balance potentiometers for:

  • Reaching a proper balance between left and right channels;
  • Compensating the level differences between various recordings;
  • Controlling the power supply DC input level;
  • Controlling the output level of the amplifier (if correctly sets)
I'm the first and only owner. Rated 9-10 as there is a small scratch on the bottom plate, but otherwise the PL-P looks and behaves like new. This is an awesome pre-amp. Paypal fee included in price.
