About the Little Bear T7
The Douk Audio Little Bear T7 is a compact vacuum-tube phono preamplifier for moving-magnet (MM) turntables that can also operate as a tube preamplifier for line-level sources. It uses two 6J1 tubes and provides selectable phono gain of 35 dB or 40 dB. The phono input is specified for a 47 kΩ load with 220 pF capacitance; the unit has an auxiliary input and an RCA output. It is powered by an external AC 12–18 V supply. This is the Little Bear T7 tube phono preamp, not the separately named Douk Audio T7 7-band equalizer.
