To Moscow, the fee drove 17 days, the track was tracked. The price taking into account the delivery of 161 rubles. Packed in a paper bag, pupyrku and another pupyrku! Even if they jumped on the parcel, the fee would not have been damaged :) sizes 18x15mm. The workmanship is very good, there are no traces of flux. Probably, I'll add a review after the amplifier board test in the case. Who is interested in the details about how it works, and most importantly-does it work at all? -Welcome :)
