Servomex Controls Decade Capacitor Type B

This is a vintage Servomex Controls Type B decade capacitor box that's been part of a lab setup. It features three precision dials covering ranges from .001 to 1.1 microfarads, housed in a classic dark wood-style casing. It's built with a 1% error tolerance and rated for 500 volts peak. Used, but the dials still have that solid, tactile click to them. Great piece of vintage test gear for a collector or a hobbyist's workbench.
