Ninety years ago, the November-December 1930 issue of Радиолюбитель (Radio Amateur) magazine featured this 6-tube receiver named ЭЧС (EChS). While there is a rather long article explaining it, I’m not able to decipher any of it, other than to say that it appears to be a handsome well-built set.

A better scan of the article can be found at this link.  For those who can read Russian, I’d be interested in learning more about this interesting looking set.
