Active potentiometer
The potentiometer introduced by Panasonic a little while ago is of a quality exceeded only by the Iikes of the Penny & Giles potentiometer (which cost in excess of > 100). The Panasonic devices have multilayer tracks made from conductive plastics and carbon , which are linked to the terminals by silver electrodes. The five-fold wiper is also made of silver and guarantees high accuracy (tracking within 0.8 dB) and smooth operation. In other words, this is an attractive, reasonably priced, high-quality volume control.
