Excellent performer. Easily made over 100 watts from my old Harmon Kardon amp. The audio is very clean and I had no trouble biasing them. They appear physically to be a perfect clone of a real vintage 6550. This is the first good experience I have had buying new manufacture (most are non standard spec junk)) tubes.
