General purpose IR volume control

Home made audio amplifiers are rarely equipped with a remotely controlled motor-driven volume control. Curious, because motor-driven pots are highquality products, and consequently should appeal to the 'high-end' audio fraternity. Fortunately, prices of motor-driven volume controls have come down to acceptable levels, while infra-red remote controls can be obtained fairly easily from TV spare parts sources. Time to put two and two together.
