AIYIMA 2PCS MX50 SE 100WX2 Dual Channels Audio Power Amplifier Board HiFi Stereo Amplifiers Diy Kit
Sent quickly, it came also quickly,
The seller is worried about the delivery and it's nice, not yet assembled, but a bunch of details without a cassette and bent, in principle, while all the cons
Delivery is not addressable, but to the warehouse of the mist Express in 20 days, packed well, in appearance all the whole, arrived designer, the boards are very high quality, the kit is full, did not check in the work.
Got this set. While everything in the form of details, did not collect. Checked some transistors on the tester, namely weekend, ktd1047 and ktb817. As far as I know, these are good Korean transistors, and inexpensive, so there is no reason to fake them. Transistors are like complimentary, but in my case, the pairs are not selected. Separately, the parameters are ideal, that is, the two ktd1047 HFE-clearly the same, and the two ktb817 too, but the HFE differs. In this case, ktd1047-HFE 113, and ktb817-HFE 186. That in general, the nyfig is not complementary...
Okay. We will collect, and we will watch what is there and as a sound. Perhaps later I will add a tip.
Packed perfectly, everything came intact.
