This vintage Centralab R2-27 Fastatch Rear Dual Volume Control is a specialized, modular component essential for the precise service and restoration of golden-era electronics, television sets, and high-fidelity audio equipment. Part of the legendary Centralab Fastatch II system, this rear unit allows technicians to easily snap and stack secondary audio layers onto a front potentiometer setup without requiring entirely custom component casings.

Featuring a 25k Ohms resistance rating, a highly accurate C1 resistance taper, and an isolated dual concentric layout, this component is engineered to restore factory-spec sound attenuation while maintaining strict historical accuracy under the hood. It is a vital find for repair technicians looking to fix dead audio tracks or dual-control imbalances in mid-century gear.
