Audio Amplifier PCB PCB for 56W Audio Amplifier using LM3875 HiFi Amp. IC Lot Size: 2 units See other listings and lot sizes for this item See other PCB products This is a premium PCB, with space for screw terminals, zobel network, has Gold-Plated Nickel pads, BLUE Conformal coating both INVERTING and NON-INVERTING amp versions on the same PCB For LM3875 IC. High quality FR4 double-sided, plated-thru and tinned holes, with conformal coating. This PCB enables the building of either an inverting or non-inverting amp. Circuit traces and parts placement are provided for BOTH versions. You choose which parts you want to populate to obtain the amplifier you want. This is the only Gainclone PCB that allows you this flexibility. Build yourself the amplifier that sells for hundreds to thousands of dollars in various incarnations and brand names. The "Gain-clone" or "Chip-Amp" stirred a great following of audiophiles, originally inspired by the "Gaincard" Amp, a product made notorious by its exceptional sound quality --and price tag--, and which used none other than the "Overture" LM3875 Amplifier IC. below: front and back of PCB. This is one of the very few Gainclone boards that implements a ground plane, while also providing a "star" grounding point. Requires a filtered power supply of between +/- 24V and +/- 42V. Maxiumum power output attained only with supplies of +/- 32V or more. below: Schematic of the inverting amplifier implemented on the PCB below: Schematic of the non-inverting amplifier implemented on the PCB BELOW: provides for screw terminal connections (good design should not allow wires to permanently dangle from PCB, and all connections should be removeable for servicing/testing) below: also provides for pin-header connections -double row, for greater contact surface, and mechanical robustness. This allows you to place female header terminals at the ends of your wires, and make easily removeable connections to the PCB Kit available that include all components. search for K331 Kit available that inclutes screw terminal blocks, and all passive components, except for the filter capacitors, search for K332 _pcb_ I can only ship to buyer's EBAY shipping address IMPORTANT: Buyer controls combining of order, by making a single payment for all items.
