The amplifier belongs to a group of devices made in such a small number of copies that it is difficult to call its manufacturer a manufacturer. In this case, it is difficult to even talk about a manufacture. The amplifier has no markings and finding information about the person who built it caused me a lot of difficulty. It turns out that it is a product of a company (this is a bit of an exaggeration) called ARG. It is probably the work of one person, Mr. Yevgeny Kreminsky from Lviv.

At one time, fascinated by the 300B triode, a cult device in the audiophile community, I decided to build an amplifier based on this tube. As I decided, so I did. The amplifier has the form of two monoblocks. Below is a photo of one of them. I have to disappoint the purists - the monoblocks are not "visually" symmetrical, they are really identical. When you put them next to each other, they can arouse a certain distaste among aesthetes. I found out about it personally. My answer in such situations was always the same: we should listen to these monoblocks as they work together, not as they "look together". And it turns out that sometimes it helped.

As part of the descriptions of repairs of various devices (primarily tube devices), I allow myself to make a number of critical remarks of both an objective and (I freely admit) subjective nature. I simply do not like something and that's it. It is easy to criticize others, of course. It is worse when you screw something up yourself. I have many such personal failures that I keep secret. One of them is the repair of Nykiel Audio Space 3.1 loudspeakers that has been going on for ages. After several years of putting this matter off until another day, I decided that I would never finish this repair unless I had some stimulus that would pump some cosmic energy into me and pull me out of this swamp by the ears. I thought that as a test, I would first reveal the backstage of the failure that was crushing me more and more.
