The metal-bodied Noble 204Y is one of my favourite potentiometers – now getting quite rare.
10K is suitable for transistor power amplifiers.
More detail, clarity and tighter bass than Blue Alps but without the tendency to be bright/etched like a TKD.
Built into high quality black aluminium box with one input and 40 cm screened silver captive lead out to power amp to keep lead length short as befits a passive pre-amp.
Can be fitted with output sockets if required at no extra cost.
