Quicksilver Audio stocks quality replacement vacuum tubes for Quicksilver Audio products. We maintain a complete tube testing laboratory with three custom-made burn-in machines and two Tektronics 570 Tube Curve Tracers. Burned-in and matched tubes from Quicksilver will give you better performance than tubes purchased from vacuum tube brokers. You can purchase these tubes from your dealer or directly from the factory. Quicksilver vacuum tube warranty period is 90 days from date of purchase.
Output tubes:
Quicksilver Audio burns in output tubes for 10 hours, then performs both AC and DC matching tests. This improves tube performance and reliability.
