# How to Choose a Used Integrated Amplifier Please see my profile for information on price reductions. TRIODE TRX-EQ6 High-Quality MM/MC Phono Equalizer. *Includes power cable* Used as the main unit for about 4 years after measures were taken to eliminate hum noise. Initially, it was a disappointing product because the sound quality was good, but the hum noise made it unusable. I investigated the cause myself and performed maintenance. Hum noise eliminated. Built-in AC power supply for neat wiring. [Maintenance Details] Electromagnetic shielding of parasitic antenna patterns on the circuit board. The MC transformer was brought closer to the unit, and the elimination of hum noise was confirmed at maximum amplifier volume. [Specifications] Circuit Type: Semiconductor circuit MC Circuit: FET Class A amplification Total Harmonic Distortion: 0.025% Channel Separation: 70dB Input Terminals: 1 system Input Sensitivity: MM 2.5mV / MC 0.25mV Gain: MM 36dB / MC 55dB Applicable Cartridge Impedance: MM 47kΩ / MC 2Ω~47Ω Output Terminals: 1 system Output Impedance: 300Ω Power Consumption: 3W Size: Width 90 x Depth 230 x Height 100mm Weight: 1.6kg Accessories: Power cable
