I picked up a couple of pairs of these on spec because they were cheap. They don't have the usual Shuguang marking, just a sticker, which will probably shrivel up and turn brown when the tube dissipates any significant power. They came in "Shuguang" boxes, but those are easy to print up. Anyone try these? When I get home, I'll compare the plate size to some real 6L6Gcs I have hanging around.
