Yea, they are definitely an overseas type and from all that I have read, they are the same as our American types. They test the same on my testers, although I noted the 5Z4 did test stronger than a NOS 5Y3gt. The 6P3P tested like a 6L6GC. These appear to be all China made. I have had issues in the past with Chinese made tubes as far as life goes, but on the Russian made tubes - Zero problems. Here's a close up of the 6N8P tube, in which you can note that I am not using. I might later try a set of USA made 6L6GCs just to see if there be any difference in performance.
If I could find the place called "Somewhere", I could find "Anything"
