Need help w/ Audible Illusions M3A

First off I'll say that I'm new to owning tube gear and appreciate any advice Audiogoner's can give. I own an Audible Illusions M3A and it has developed some "hiss" in the right channel. It's loud enough to hear when the system is idling from 12 feet away, and therefore fairly annoying. It doesn't sound as though the performance is comprimised any other way though. Time for new tubes? If so, any suggestions?

Thanks in advance,

Scott

yes the gain switches are in the preamp. I am running amperex bugle boys. You will need to make sure that you are flipping the correct switches because there are 4 switches two for the gain and two that are for by-passing the capacitors.

Well I think you got bad info on the bugle boys because mine have been in my M3A for 2mos. and still sound as good as the day I put them in. I do use a set of pearl tube coolers, also I leave the pre-amp on at all times. I also have had success with telefunken tubes, but I thought that the bugle boys sounded better. just MO
