A lot of hi-fi buffs believe that a volume control made from a resistive ladder gives the ultimate in reproduction. Trouble is they are expensive and hard to build. This project is neither. It can be easily built in a couple of nights, all you need is a drill and a soldering iron. And if you need at kit check out my website
which features this and other diy audio designs you might find of interest.
The only compromise made in this design is to use 5db steps rather than the standard 3db. This means that the whole thing can be fitted around high quality 12W rotary switches. 3db steps are, in any case rather small. 5db steps are rather more definite nad when you get used to it more satisfying.
