Need help identifying type or class of new tube amplifier

Several months ago I purchased a used integrated tube amp and asked for assistance identifying the manufacturer. I've given up on that approach and now would like only to identify the type of amp that it is. It appears to be Russian with the only English designation being "Moonrower", Moscow.  The tube layout is as follows:  Power tubes - 4 X Millard 6L6 GC;    Input 1 - 2X  Amperex EF86;   Input 2 - 2X 6DJ8. 18 other interchangeable power and input tubes were included.  This amp has separate L and R volume controls. I don't know how the previous owner made the determination but he said the power rating is 30 watts. My primary amp is a Cary with all 4 input tubes the same so I was doubly confused when I saw that this one has two different types. Any help will be very much appreciated.
