That amp can also handle the KT88 but check out the KT 90-type 3 from upscaleaudio.com - a great sounding tube. The 90 is also compatible with that amp.
McIntosh MC275, which tube works the best?
I have the new version of the MC275 (with balance inputs, stainless steel chassis). I am using the 6550c tubes that I purchsed with the amp. I believe they are made by Svetlana, but with McIntosh logo printed on the glass. Thinking about replacing the 6550Cs, any suggestions?? thank you.
