[COD] AqToCna Ship within 24 hours TDA7379 Stereo Power Amplifier Board Module DC 12V 39W+39W NE5532 Preamp Speaker

Feature:Adopt newly imported TDA7379 amplifier chip, equipped with heating NE5532 preamplifier.R8, R10 are the magnification setting resistors (the default transmission is about 2-3 times magnification, according to their needs, change the magnification from 10k-47k resistors to choose between, the larger the resistance, the higher the zoom factor, if you use plug-in resistors , The chip resistance can be removed from the original, the plug-in resistance welding position is pasted on the patch end)The input and output coupling capacitors of the preamplifier promise imported heating capacitors, which are superior to the polarity effect.Maximum output power: 39W + 39WWorking voltage: DC 9-17VBoard size: length 50mm and width 33mmNote:In this section, the amplifier board has no heat sink. The tester in front of the amplifier board must be equipped with a large enough heat sink.Package Included:1x TDA7379 amplifier
