Note on 3 Jan 2016 : The filtering e-caps are now 3300uF 50V Panasonic industrial grade capacitors instead of Rubycon in the pictures. This is a partial kit of LM4780 stereo power amplifier. LM4780 has been one of the most successful power amplifier IC for its simplicity of building and sonic quality. This is a stereo design. It can also be configured as a single channel parallel amplifier. The kit contains all components, EXCEPT the LM4780 IC. This kit features high quality components : Elna and Panasonic E-caps; Panasonic non-inductive power resistors; 1% metal film resistors; Aerovox film cap for coupling; On-Semi good sounding rectifier diodes. All the components are as shown in the pictures. Power supply : 28Vx2 AC, 5A. Board Dimension : 144mm x 64mm. Thickness : 2mm. The PCB uses 70um thick copper ( 4 times normal thickness) and is gold plated. We provide schematic by EMAIL to buyers( to be attached with the shipment notice). We do air shipping worldwide at US$7.50. We welcome combine shipping. Powered by SoldEazy
