Co., Inc., Everett, WA Lines: 25 If you're favorite amplifier uses KT-88s for output valves (tubes) (like the McIntosh 75 and 275, or Dyna Mk-III, or Citation II), and you haven't switched to 6550s yet, then you ought to call your favorite tube monger and order your last sets of KT-88s before there aren't anymore to be had. According to a news item in Studio Sound, a British audio magazine, the M.O. Valve Company recently announced that it was ceasing production of the KT-88, which it has manufactured for the last 30 or so years. Now the KT-88 is already hard to get, and this should make them even harder to get. (not to mention what will happen to the price!) If your amplifier uses these valves, you can use 6550's instead. There are some spec differences, and many folks claim to hear the difference. But the bottom line is that the 6550 will work in the same socket. If you are one of those folks who can hear the difference, then kindly detail your findings to the net, but please don't flame at me. Rick Chinn John Fluke Mfg.
