Replacement of the vacuum tubes

Similar to a light bulb, vacuum tubes have a certain life cycle and have to be replaced after a period of time. We guarantee the product for 12 months after purchase or 2000 hours of usage. However, most of our vacuum tubes live much longer. When the tubes are new, the ampere meter will show 80 milliampere.

When it displays less than 60, it's about time to order new ones. In Switzerland, after you purchase our tubes, we will deliver and install them for you at no charge. For international orders, the vacuum tubes will be shipped to you in a secure appropriate parcel.
