Valve Single Ended

About the Valve Single Ended

The Parmenter Valve Preamplifier Single Ended is a purist stereo tube preamplifier featuring a pure class A, transformer-coupled, single-ended circuit built around high-quality vacuum tubes. It uses a tube rectifier power supply and premium output transformers made with high-purity enameled copper wire and ultra-linear laminations from Hitachi metals. The design emphasizes low noise, high fidelity, and natural sound reproduction. It includes a 4-input selector and a 48-stepped attenuator volume control with remote control capability. The preamplifier is constructed with high-purity copper solid-core wiring in both signal and power supply units, ensuring minimal signal loss and distortion. It offers a maximum voltage output of 20 Vrms, input impedance of 100K ohms, output impedance of 220 ohms, voltage gain of 12dB, and a frequency bandwidth from 10Hz to 110kHz. The unit dimensions are approximately 440mm wide, 192mm tall (with feet), and 445mm deep, with separate power supply and signal units weighing 30 kg and 26 kg respectively. The preamplifier is available in silver or black front plate colors and supports factory-set voltage options for 110-120VAC or 230-240VAC operation. This model is designed for audiophiles seeking a refined, natural tube sound with robust build quality and precise control.
