MA2275 Issue need some advice

Looking for some advice. McIntosh MA2275 integrated and the left channel sounds dirty, at higher volumes the bass sounds staticy and broken, almost like a blown speaker. Using B&W 805D's, swapping the speakers the problem is still there but on the other speaker so its coming from the amp and not the speaker. Do the tubes need replacing?

Try switching your tubes around to see if the right channel has the same issues.

Yes, it could be a tube but I have also heard a bad resistor sound like this too.

Also, check fuses.

Thanks everyone for the replies, will change the tubes around and see if I can isolate the problem. For the fuses, I'd think they would work or not work (blown). Is there something to look for in particular? This is my first tube source, but in general how do you know that the tubes need to be replaced? Thanks!

OK changed the tubes from right to left and still having an issue on the left channel. Does anyone know if the MA2275 shares any of the tubes?
