Yes, there must something wrong with your equipment. There is no way that you should be replacing tubes so often! I have a MD 106T and the tubes are probably going on ten years and the tuner still sounds fine. I play it on average about two hours a day, so you can do the math. The tuner has a slow turn on which contributes to a long tube life.
What are some of the better tuners out there?
What are some of the better tuners out there? I am enjoying my Magnum Dynalab MD106T. I find myself at the mercy of reception and clean ac but when all is right the sound is quite nice. I’ve found good results with Amperage tubes but I find tubes too inconvenient in that they burn out too quickly.
