The Manley Shrimp preamplifier featuresVery short, simple minimalist signal path. All-tube design. 2 x 12AT7 input, 2 x 5670 driver, and 2 x 7044 output. The signal path furnishes very high dynamic range with prodigious input and output signal headroom.

Upscale Audio has the largest selection of the coolest NOS 12AT7 tubes on the market to make this preamp absolutely sing!

Signal path also delivers high bandwidth, low noise, modest local negative feedback and low distortion, and is voiced for best musical performance.

New Radio-Frequency based remote controls the silicon-free high-quality motorized attenuator set, for infinitely resolvable control of listening levels. No need to "point" the remote in any direction. Now the Shrimp's attenuator set can be controlled from another nearby room, through walls, floors and doors, and through opaque equipment closet or cabinet doors too!

Dedicated White Follower stage using the 5670 dual triodes effortlessly drives all passive interstage circuits; volume, balance and output stages receive crisp instruction from the Follower regardless of control settings. The White-follower output stage provides low 50 ohm output impedance. This is much better than a boring plain ol' cathode follower. The Shrimp can drive anything, not to worry.

Generous energy storage via large power supply capacitors for more impact in the bass. No global feedback makes the Shrimp very fast sounding. Non-inverting two-triode gain stage is direct-coupled for most pure signal path. Filament supply floated 80V above chassis ground for quieter operation and longer tube life.

ALPS audiophile-grade balance and motorized VOLUME pots. MIT/MultiCap polypropylene audiophile-grade signal coupling capacitors, including two 30 uF monsters on the output stages. Warm-up delay / MUTE button. Features and quality components usually not found on entry-level pieces.

  • Operating Mains Voltage: Units are purpose built for original destination country's mains voltage: 100V, 120V, or 220-240VAC as indicated on the serial number badge. Power transformer must be replaced in order to change mains operating voltage. 120VAC units may NOT be rewired to put the primaries of the power transformer in series for 220-240V operation or a large radiated field of hum will develop. If changing locations/voltages, the power transformer must be replaced with the dedicated one for the voltage at which it will operate.
