Service was excellent from purchase to delivery... Great Stuff
Tested this LM386 over the weekend as I want to use it for a Turntable Pre Amp, mine is moving magnet.
There are many grounding sounds and I used 9v supply on these boards.
I eventually eliminated some of the grounding sounds and there is a very faint ground sound coming through.
it's recommended to use a preamp specifically designed for turntables or a dedicated phono stage, rather than the LM386, for optimal performance.
The LM386 will work nicely with driving speakers of 1W and not as a preamp.
Used 2x LM386 modules to build a Pre Amp for my Turntable. The cartridge on my Turntable is a Moving Coil type and the 350mv induction on the input side is sufficient to charge the coils for a 35-40db gain at 75%. These modules like Very Clean DC input so I would recommend you use a well regulated input voltage. Tested mine on 12.6V and it was not ideal, over voltage, would recommend 7.5v 1A. Happy with my purchase.
