THANK YOU!...

...for choosing The MANLEY STEELHEAD phono preamplifier

.

  Please read over this

manual carefully as it contains information essential to the proper operation and maximum enjoy-
ment of this fabulous 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 STEEL-
HEAD 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
and adaptability.

UNPACKING

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 unit is damaged or fails to operate, notify the shipper or your
dealer or us or your local authorities immediately. Or if you suspect The Shipping People threw it
off the airplane and onto your front porch whilst flying overhead at 30,000 feet, notify the ship-
ping company without delay and complain to them as we only guarantee this unit to be able to
survive a drop of 23,487 feet or less.

Your STEELHEAD was packed by Manny Q. with extreme love and each box includes the

following components and accessories:

a) 1 each, 6 foot IEC 3-conductor mains power cable (that you will probably replace with an

expensive audiophile cord anyway.)

b) 1 each, Owner’s Manual per pair (that we hope you will keep reading.)
c) 1 each, Outboard Power Supply Unit with captive grey power cable and big fat connector.

It is prudent to retain the shipping materials for future use, as they are custom-formed for the

preamplifier and will greatly minimize the chance of shipping-related damage should you ever
need to put your precious Steelhead in the careless hands of The Shipping People again.
