Replacement Vacuum Tubes

Sure, you could get pig-in-a-poke tubes for less elsewhere, and then you’ll have the fun of matching and evaluating them. Or you could hope that you don’t notice the difference between channels or the background noise.

Keep your equipment operating at peak performance by getting high-quality tubes. We take the time to carefully evaluate all vacuum tubes in-circuit, selecting for low noise, low microphonics, and high gain. Pairs of tubes are further matched for balanced behavior in circuit.
