The amplifier was ordered by ePacket and came in 12 days. The first inspection of the board showed good soldering of components and a slightly irresistible flux. Included are silicone gaskets fastening to the radiator. To check, I assembled a stand from a transformer with two 25 v windings and temporary capacitors at 220UF. The first inclusion was successful. Even in such small containers, when the input is closed, the amplifier does not issue absolutely no goals and noises! Very competent distribution of land on the board. The sound is very good, clean. The amplifier does not make any distortions from itself, which is very pleasing. The kit was purchased to replace the amplifier unit in Odyssey -010. I think it's a great replacement. To review I attach the amplifier scheme:

Very good quality boards. Sending, shipping is fast.
I put it in Vega, instead of the regular ends. The power wires changed to a decent section, in fact, paired with S90, the fan made such a sound, which was not supposed to be her inventions. Fire!

Packed in a box of dense cardboard and wrapped in a thick layer of cattle. Inside each amplifier is wrapped in a bubble film. Also in the film are put terminals on the board and dielectric. Gaskets for weekend transistors. Very quality soldering. Everything is entirely safe. Not yet connected. The first impression Ooo very positive!

Everything got. Delivery at height. Everything is packed. Not the first time I take this seller. Always fast delivery. No oscilloscope. Estimated power at 50 V by 4 Ohm 150w. The potentiometer handle is not turned to full volume. I didn't get back to the end. Load resistance has been smoothed. I had to stop the experiments.

The picture in the app seemed that it was more. But it's even plus that the amplifier is so compact! Was wrapped in purple and put in a carton box. At first glance like everything and soldered well. Until I connect-I can't find the power. In our "dolghoevo" about DC 56V no one even heard. I will also order with Ali.

Good and powerful amplifier. Fed 40 V in the shoulder. The only thing I thought was missing the bottom. He took the puffiness, glued it himself, immediately got in. On the hearing of 50-60 watts per channel. It's not hot. I will measure the exit-add the review.

It all came until I checked it out. Judging by the previous order, everything should be fine. It is desirable to establish protection.
