Further details for this manufacturer by the members (rmfiorg):

Here are photos of a couple of K-R Tubes. There is a note on the flap inside the box which states that "This tube uses inventions of United States patents lisenced to Sylvania Electronic Products Incorporated and The Radio Corporation of America" The 6SN7GT tube appears to be a Sylvania tube. The code on the top of the tube is C3M. Both tubes were branded with a yellow K-R logo which is faint and rubs off easily.tbn_usa_k_r_tubes.jpg
