Hello!
Dear friends, please help to find the circuit diagram, scheme of an power amp A-80. Buying this amplifier, i wasn't attentive, instead of a collected payment the designer bought. The guides to assembly aren't present, I don't know what face values of details where to establish.

As you can see by the brand, this kit is supplied by Hifidiy.net. It is sold by many Chinese resellers and they usually post the schematics on their websites. That's where you look.
Here is one such Aliexpress website with a schematic: HIFIDIY A80 hiend amplifier kit 100W*2 8ohm H140 circuit amplifier-in Amplifier from Consumer Electronics on Aliexpress.com | Alibaba Group
From the amplifier design point of view, it is claimed to be a development of the basic H140 kit and that was itself a simplified Naim NAP 140 design. However, the design appears here, to be the generic EF "Blameless" style schematic. So the description is quite misleading.

Ian thank you.
I already saw this scheme, but unfortunately it isn't read also the most important that in it there are no face values of details. On the site hifidiy.net this product too isn't present. Probably it is necessary to try to contact the site administrator.

At the moment any of sellers or administrators of shop didn't contact me.
On the Chinese resource I found the fullest version of the description with photos on assembly of the amplifier.

DropMeFiles ? ?????????? ????????????? ??? ???????????
Link to Multisim file.
But also there the schematic diagram with face values of details didn't appear. But by means of photos and logical conclusions I could restore approximately face values of resistors on color designations.
In the Multisim program I restored the scheme and I brought face values of details. I am not so cool as local old residents therefore I want to ask to help experts to look at the scheme and to find possible mistakes. If I am mistaken at assembly it will be fatal to me.
I translate into English by means of the translator, excuse!
