I have some Hafler stamped 2SK134 and 2SJ49 from a DH-220. A few years ago I replaced them with Exicons when one of my 2SJ49s tested bad. I can send you two of the the 2Sk134 if you want them. I know they don't have "Hitachi" printed on them, but they are certainly originals. I only did rudimentary testing of them with a little transistor tester. You can choose which two you want. Just PM me your address.
