The Telefunken tubes I have been using for years always gone bad within a year. How long should tubes last in the MD106t tuners?
Which tubes best for Magnum Dynalab 106t tuner?
Which tubes are best for Magnum Dynalab 106t tuners? I have used Telefunken from Magnum Dynalab directly with mixed results depending on which quality tubes. Since Covid I found myself searching tubes from a different source and am now using Amperage tubes which are quite nice. Which tubes do people find the best for the Magnum Dynalab tuners?
