Product Details

The hunt for an affordable but world-class vacuum tube phono stage is over! Direct descendant of one of the most highly respected phono preamps in the world - The Steelhead - we present The Manley CHINOOK. Featuring Stereophile Class A Recommended Components and winner of Absolute Sound's Preamp of the Year award, the Chinook epitomizes the sound of the Steelhead.

Like the Steelhead, each channel employs the two triode sections of a 6922 for amplifying duties with highly accurate passive RIAA equalization networks. In the Chinook, the signal is then directly coupled to another 6922 dual triode serving as the output driver in a White Follower configuration. This output stage circuit provides super-low output impedance and beefy current-driving capabilities. It can drive long cable lengths and difficult loads, tube or solid-state.

Setting up the Chinook could not be easier. There are two internal settings for optimal gain: 45dB for Moving-Magnet cartridges and 60dB for Moving-Coil cartridges. Simply set it and forget it! The back panel contains DIP switches for adjusting the input resistive and capacitance loading values. 31 possible options between 26 and 800 Ohms plus 47k Ohms and 7 capacitive loading choices between 50pF and 350pF provide you with the flexibility to match any cartridge and fine tune the tone. Audiophile-grade and proven components are used throughout, embodying Manley's dedication to seductive sonics, combined with the reliability that professionals around the world depend on. At just about a quarter of the price of the Steelhead, the Chinook's focus is on elegant design, high quality componets and excellent sonic capabilities.

Designed and built in California, the Chinook exemplifies Manley's commitment to quiet simple and clean signal paths. The Chinook demonstrates the supreme linearity of vacuum tubes while providing the flexibility needed to embrace any turntable setup. Everything from the most exotic 180 gram audiophile pressing to 25 cent thrift-store classics will be reproduced accurately and musically.

Technical Specifications

MANLEY CHINOOK PHONO STAGE
