rogue audio m150 owners

I have rogue audio m150 monos that are a little over a year old , today I measured my power tubes on a tube tester and I was suprised that my tubes were barely testing "good" . they seemed to have lost most of there power. the tubes are EH kt88s . is this normal ? how many hours is average for this type of tube ? I am new to the world of tubes and I thought I would get 3-5000 hours of good use before needed replacement. Also, have any m150 owners tried any different brands of tubes? Is there one that stands out from the others? please help ! thanks and happy listening!

First check your incoming power. You might need a variac, or better still A PS Audio Premier Power Plant to both regulate and clean the power.

Tube life depends on how much you play them and how hard you drive them. That said, some tubes last longer than others.

FYI: I replaced my M 150s with a number of early generation class D amps, and have not looked back. Better performance, saves on electricity, and no tube hassles.

I now use a Wyred 4 Sound MC 250/500. Lots of current reviews to wet your appetite
