I have a MA2275 and changed the chinese tubes. Used NOS Telefunken 12AX7 for V6 & V7, these are the preamp tubes, which when changed make a world of difference. The 12AT7 are the left & right channel driver tubes with NOS Telefunken and absolutely love it. I didn't change the V4 & V5 because these are the phono stage and I'm not using them right now. I bought tubes from Brent Jessee Recording Supply.

As implied in the above responses, replacing the small tubes will have a larger impact than replacing the KT88. You can go to audiokharma McIntosh forum and read about this till you get exhausted. Above recommendations are good, though.
