Description

AC power supply: 100V-240V Audio Input: 4 groups * Stereo L/R RCA Audio Output: RCA Frequency Response: 10-26kHz (+/- 0.11dB), about 15 times voltage amplification Total Harmonic Distortion: 0.078% Signal to Noise Ratio: 99dB Input impedance: 100k Ouput impedance: 10k Gain: about 11dB Chassis Dimensions: 320mm*170mm*50mm Weight: 4KG Features Using Japanese original ALPS 16 Type 15mm 100k Duplex potentiometer, switch is produced by Taiwan-funded factory. With 4 groups of RCA audio input, convenient to compare different audio source and no need to plug-in and out the cables repeatedly. Gold-plated terminals to guarantee lossless transmission. Using 0.8mm stainless steel CNC punching chassis, its SNR up to99dB, the background is extremely clean without any noise. Using WINA MKP10 0.1uf capacitors, 0.39u Swiss RIFA PHE 426 series, IT 2.2uf capacitors, etc. Power transformer uses H360 0.5 piece 76 * 40 core, especially with double shielding layers GND，grounding line is yellow-green line outlet. A group of filament 3.15v * 2 for 3*12AX7 filament power supply, high-voltage 270V * 2 uses 6Z5P tube rectifier. Amplification circuit using scaffolding of welding. Packing 1*Full set DIY KIT of tube preamp This is a kit, which mean you will receive a pack of components, you will need to solder them together before use, the image is only for reference how the item will be after soldered, not what you will received.
