🔊 Youliang 2pcs 20 Times LM386 Audio Amplifier with Adjustable Resistance for Enhanced Sound Experience Review

I can't say for sure that I didn't do this when putting the components together but none of them worked. In one of them you can only make out faint sounds above hiss and pop.

They are ok - they get 2 stars because they are missing 2 capacitors that keep the amplifier stable. I had to add them myself. Without them, the amp hums like crazy. I don't know why they dropped the parts. There are many other suppliers of an almost identical piece of equipment, if your speaker hums from this either add a compensation capacitor or buy another brand that will completely fill the circuit boards.

This is a base board with a wide input voltage range. it's important that you stay indoors and out. nice easy to use package.
