Reference Marantz M7 Circuit Preamplifier DIY Kit HiFi Audio 12AX7 Tube Preamp

Description: Product Details: Note: This is a DIY Kit, you need to solder assemble it yourself. Based on Marantz M7 pre-amplifier circuit. Japanese original ALPS 16 type 100K double potentiometer with 15mm shaft length. The 0.8MM brushed stainless steel plate CNC stamping chassis makes the signal-to-noise ratio up to -99dB and the background is extremely clean. The power transformer uses H360 0.5 piece 76*40 iron core. The primary is two sets of 110v, the series connection is 220V, and the parallel connection is 110V. The secondary filament winding is especially grounded with a double-layer shielding layer, and the grounding wire is a yellow-green wire. A set of filament 3.15V*2 for 3 12AX7 filaments (12AX7 4+5 and 9 feet are 6.3V) High voltage 270V*2, using 6Z5P electronic tube rectifier. The amplifying circuit is welded by scaffold bars, and the power supply uses PCB. 4 groups of signal input, 1 group of output. Use WIMA MKP10 0.1uf capacitors, 0.39u Sweden RIFA PHE426 series, IT 2.2uf, capacitors and other audio dedicated capacitors. Applicable to global voltage standards, (110V/ 220V through wiring method) The size of the chassis is 32*17*5cm, and the height is about 10cm. The height of the machine should not be less than 18cm. Specifications: Working voltage: AC110V or AC220V~240V Input socket standard: RCA (4 inputs, 1 output) Frequency response: 10-26kHz (+/-0.11dB) Voltage amplification is about 15 times Total harmonic distortion: 0.078% Signal to noise ratio: -99dB Tube: 12AX7B * 3, 6Z5P * 1 Package list: 1 × Tube preamp kit (including tube) About Us :We are dedicated to offer the best audio-visual products at the lowest price to our customers.
