I had M-150s' for three years and had to re-tube them every year.
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!
