Audio Research Amps
Using our knowledge and experience, we've selected vacuum tubes to create Upgrade, Premium, and Ultimate tube kits/packages that will work great in your amplifier. Re-tubing your Audio Research amp has never been easier… More Details
Many consider Audio Research founder William Z. Johnson to be the father of modern high end tube audio. When mainstream audio companies were going solid-state, Audio Research was determined rather to produce superior sounding vacuum tube amps.
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 Audio Research 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 Audio Research amps when available.
You can learn more about Audio Research tube amps at the Audio Research Corporate site. Another excellent resource is the Audio Research Database. A brief history can be found at Wikipedia.
