Manley JUMBO SHRIMP Line Preamplifier

In Stock	An In Stock item is available to ship normally within 24 business hours.
Preorder	A Preorder is an item that has not yet been released. Typically the label will set a projected release date (that is subject to change). If a projected release date is known, we will include this in the description in red. Other Preorders are set to release 'TBA.' This means that release date is yet 'To Be Announced'. The Preorder can be released anywhere between weeks, months or years from its initial announcement.
Backordered	An Out Of Stock item is an item that we normally have available to ship but we are temporarily out of. We do not have a specific date when it will be coming.
Awaiting Repress	Awaiting repress titles are in the process of being repressed by the label. No ETA is available at this time.
Expected On	When an item is Out Of Stock and we have an estimated date when our stock should arrive, we list that date on our website in the part's description. It is not guaranteed.
Special Order	A Special Order item is an item that we do not stock but can order from the manufacturer. Typical order times are located within the product description.

Description

The short, simple, minimalist signal path delivers high dynamic range with prodigious output drive capability. Its focus is on high bandwidth, low noise, modest local negative feedback and low distortion - voiced for a clean musical performance. The White Follower stage using 5670 dual triodes effortlessly drives the passive interstage volume control. Quick, alive, transparent with good rhythm and extension. RF Remora Remote control included.

Features

Very short, simple minimalist signal path.
All-tube design: 2 x 12AT7 input, 2 x 5670 driver, and 2 x 7044 output.
Signal path furnishes very high dynamic range with prodigious input and output signal headroom.
Signal path also delivers high bandwidth, low noise, modest local negative feedback and low distortion, and is voiced for best musical performance. Radio-Frequency based remote command of the silicon-free high-quality motorized VOLUME 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. 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. Cool 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. Filament supply floated 80V above chassis ground for quieter operation and longer tube life. ALPS audiophile-grade balance and motorized VOLUME pots. Manley uses the nice parts in here! 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.
