...for choosing The MANLEY STEELHEAD phono preamplifier. Please read over this
manual carefully as it contains information essential to the proper operation and maximum
enjoyment of this instrument.
The MANLEY STEELHEAD is designed to provide that rare combination of maximized
sonic performance coupled with a generous ability to adapt to any moving magnet, moving coil or
iron vane phono cartridge you may wish to use. With the STEELHEAD-™s feature compliment,
you no longer have to settle for what a given cartridge sounds like with a fixed predetermined
preamp load impedance, or wonder what that same cartridge might sound like when presented
with different loading arrangements. What best suits your particular phono cartridge, system,
listening room and personal preference is now merely a flick of a switch away! The
STEELHEAD adapts to accommodate your situation, rather then the other way -˜round.
To this end you will notice that it is the anticipation of your preamplifier needs which has
driven every detail of the STEELHEAD-™s planning, engineering, styling, operating convenience
Unpack the preamplifier carefully and make sure that all supplied accessories are present.
Examine all items for any possibility of shipping damage. All six tubes should be standing at
attention in their sockets. If the preamplifier is damaged or fails to operate, notify the shipper and
your dealer or us immediately. Or if the preamp was shipped to you directly, notify the shipping
company without delay.
Your STEELHEAD preamp was packed with the following accessories:
a)1 each Power supply unit with interconnect cable.
b)1 each 6 foot IEC 3-conductor power cable.
