Break in tubes? Freeze the tubes? Dear Dr. Jon Wong, Is there another way of running in tubes without using existing components to dol it. Thanks! TS |

Hello TS!
Well, you can get someone to build a tube burn in machine for you. It should have a power supply for the filament, and a B+ high voltage supply. Then it should drive a dummy load for say about 48 hours. Sounds troublesome, I would rather burn them in on the power amplifier... Anyway, if you have some new tubes, have you tried ‘freezing’ your tubes before using them? I used to freeze my tubes for about a week, then slowly defrost them. When they are at room temperature for a few days, and are completely dry, I burn them in on the amp and they sounds wonderful. Have you tried that? This is borrowed from some British fanatics who freeze their tubes in liquid Nitrogen. I wonder how the tubes did not crack. Anyway, they claim the sound is more superior. |
