McIntosh MC275


Hi all. I recently purchased a used MC275 in very good condition. The original owner said he had it service not too long ago. The amp appears to work fine but the tubes are very dim. I had them tested and they are fine with about 1/2 life still on them. Not sure what to do. Do I need new tubes or is there an adjustment I need to make? If I need new tubes then could someone give me an idea what to get and where to place them on the amp (which slots)? I want quality tubes so please, ANY guidance would be appreciated. Thank you

What version MC275 did you buy? The tubes tested fine so I would not worry. How does it sound? Is this the first tube amp you’ve owned? 

McIntosh amps are usually very easy on tubes. If it sounds great, and the MC275 amps do, enjoy it.

What speakers are you using?
