[Blossom] 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: 39W39W. Working voltage: DC 9-17V. Board size: length 50mm and width 33mm. Note: 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. Feature: Adopt newly imported TDA7379 amplifier chip, equipped wi
