This kit was designed to restore optimum performance to your blackface amplifier by blueprinting the phase inverter. Many of these resistors have drifted over time, and returning to spec (along with balancing where important) restores your vintage blackface amp and brings it to another level regarding tone and performance, sounding as good (or better!) than ever.
