Preamp Tube Bias Resistors (cathode)
Dial in your preamp tubes!
Our preamp tube bias resistors have been measured & selected to properly bias your preamp tubes. This really dials in some serious tone. Many of these resistors have drifted quite a bit over the years. Bringing them back to where they are supposed to be makes a huge difference in the tone of your preamp tubes! Includes a full set of 1/2w carbon comp resistors for your preamp, measured & specifically selected for this job.
