56W Power Amplifier Kit Power Amplifier KIT using LM3875, 56W rms Audio HiFi Amplifier, Low THD, K333 Lot Size: 1 units See other audio amplifiers LM3875-TF "GainClone" on best quality Blue Gold-plated epoxy PCB, with 4x 2200uF 50V Japanese Low-ESR capacitors 56W rms, into 8Ohm, 1 Channel 0.01% total harmonic distortion, >92db SN ratio. TO220 insulated case Uses the "Overture" LM3875 Power Amplifier IC. Requires soldering. Build a professional, high-end audio amplifier that is fully short-circuit protected, thermally protected, and performs on par with audiophile HiFi sound equipment. The kit enables the building of either an inverting or non-inverting amp. All parts are provided for BOTH versions. You choose which parts you populate to obtain the amplifier you want. High quality FR4 double-sided, plated-thru and gold plated holes, with blue conformal coating, solder mask and silkscreen. The Printed Circuit Board implements a ground plane, and "star" grounding. 2 individual amplifiers can be paralleled for double the power into 4 Ohm loads National Semiconductor document on BPA200 Bridge-Parallel 200W+ Amp http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180660529546 Kit contains PCB, all parts, and 5-page instruction sheet, for ONE CHANNEL of the amplifier. Heat sink and power supply not included. Requires a dual 30V to 43V DC power supply. PCB is double-sided ground-plane FR4 epoxy, gold plated over nickel. Film capacitors are high quality polymer film, all resistors are low-noise metal film. 2 Surface-mount 1uF 100V MLCC bypass capacitors provided. (value $4 each) 4 High quality 2200uF Low ESR Japanese SXE series capacitors made by Nippon ChemiCon, for a total of 4400uF pulse energy power on each rail for fast bass transients. 2 Surface-mount 2.2uF 50V MLCC bypass capacitors provided. (value $4 each). Below an example of completed amplifier with added heartsink - HEAT SINK NOT INCLUDED IN THIS EBAY LISTING Heat removal solutions are dependent on enclosure choices: (large, small, ventilated, slim ) and will dictate choice of cooling- such as a small heatsink with a low speed fan forcing air over it, to achieve a slim case configuration, for example.
