This amplifier is complete and worked very well in a TRF radio receiver designed here. I replaced the trim pot with a chassis mounted volume control. If I were to build another (which I will) I would simply wind the trim pot for maximum gain and place a volume control on the input connector. Easy to use. There is also provision on the PCB for the components needed to bring the gain up from 20 to 200. I did not use that facility.

You can use this small amplifier in you projects with no doubt. You need to make your own input/power supply connector(it is not included in the package). I'll show you the idea to make a set for your reference. Please see the pictures.

Small, X200 gain audio amp. You can remove R1 to get X30 Gain. Surface mount LM386 good only for about 1/2 watt.

O amplificador está normal, mas você precisa pegar energia caso contrário, ruídos

усилитель нормальный но нужно подбирать питание иначе шумы

Até agora, parece-me bem. Tentado apenas um módulo. Eu vou relatar mais tarde, quando eu tentar alguns dos outros.

Seem ok so far. Only tried one module. Will report back later once I've tried some of the others.

Haven't test it yet but pretty sure it's going to work. going to bring an old LP player back to life.
