LM1875 after pure grade DIY finished amplifier board including the radiator amplifier board
1: The board uses 1.6 mm two-panel design, high-precision metal film 1% error importing Japanese KOA feet blister resistance, small capacitance of Japan Chemical fever tonic audio capacitor, Japan ELAN capacitor filter (3300UF X 4) WIMA coupling. 2% silver solder wire welding.
4: The new batch power with the original IC, never use the bulk IC IC or grinding circuit board no disassemble the components used
The board as a whole class of materials, circuit design and reasonable quality pure Tian Run, the details of outstanding performance. Is a cost-effective HIFI amplifier, suitable for 3-5 inch speakers use.
Output power: 35W +35 W power without distortion
Output Impedance :4-8 Europe
Amplifier board input voltage: 9V-18V Dual AC input.
Amplifier board size: 105 * 55 * 45 Length * Width * Height
Even cooler Size: 112 * 80 * 60 (mm) Length * Width * Height
Model: LM 1875 stereo power amp plate after fever pure (finished board)
Of high noise ratio, close to the speakers are hard to hear noise
Installation Notice: 1875 IC with negative pressure, radiator, such as grounded, needed mica screw sets will be IC and radiator isolation, not side to immediately burn IC
