EAR 88PB Phono Preamplifier

The EAR is a switchable moving magnet/moving coil phono preamplifier. The volume control allows direct connection to a power amplifier. A buffer stage follows the volume control, using an output transformer which provides balanced or single-ended output at low impedance to drive long cables. Two inputs, one with switchable gain and input impedance (internal). Mono/stereo switch.
