Description :
The Feather 1 is a Class-A preamp which uses a pair of 12AX7 double triodes. The unit relies on an external power supply for operation or alternatively, through a dedicated connection to the Power 35. Remote control for the volume potentiometer is optional and as one would expect from its name, the unit is rather lightweight. Inside are two very neat PCBs, one housing the power supply and main audio circuitry, while the volume potentiometer and source selector occupy the other. The egg-cup-shaped volume control on the front panel is smooth in operation, but heavy to the touch, while a toggle switch provides tape monitoring. Source selection is done via a stiff dial on the top of the enclosure. The Feather One line-level preamp and the Power 35 stereo power amp complement each other. They both deliver a clean sound with fine-tuned treble, adding control to produce bass free from rumblings.
