Conrad Johnson was founded in 1977 by Dr. Lewis Johnson and Dr. William Conrad. For years they have been known to offer excellent high-end audio tube preamps and tube amplifiers.

Our tube replacement packages are designed for your amp and come in different option levels ranging from Upgrade to Premium to Ultimate. With this, you can get improved tube amp sound quality and still meet any budget.

We have found that our Premium Packages are what most customers choose. These tubes will provide your Conrad Johnson amp with great sound for a reasonable price. For those who need to re-tube for less, our Upgrade Packages consist of excellent sounding amplifier tubes for lower cost. If only the "best" will do for your beloved tube amp, we have Ultimate Packages that include NOS made vacuum tubes whenever possible. In cases when NOS tubes are not available, current production tubes of the highest quality are included instead.

Be sure to look at the Additional Info tab when viewing a tube package. This tab will provide bias information and other worthwhile information about Conrad Johnson amps when available.
