Manley produced the first modern 300B high-fidelity amplifier, the first modern high powered tube power amps, the first new power tube design in thirty years, the
KT90. Manley was also first to utilize the ULTRA ANALOG™ converters in the USA
and the first in the world to show a converter with tubes. They just invented a
new thing with the Passive Parametric Massive Passive... this is all old
news....
"First" is exciting. "Best"
is the real goal. "Affordable" is honest business. "Most
Expensive" is for others, not Manley. They do, however, indulge in just a
little "audiophilia nervosa": high purity wire, gold contacts, good
layout, hand soldering and wiring, overkill power supplies, silver solder, 1%
metal film resistors, film & foil capacitors, selected tubes, solid chassis,
etc. They do all of this sincerely for the music, and for their customers.
PHONO STAGES
 Steelhead Phono Stage
Debuted to the world this
very cool phono stage at CES 2001. The Steelhead is an "upstream"
device and has two Moving Coil inputs with
selectable impedance load 25, 50, 100, 200 and 400 ohms via Mr. Clever
"Steelhead" transformer/autoformer. It also has variable and
selectable Moving Magnet input impedances too 25, 50, 100, 200 ohms and 47Kohms.
Very nifty is the selectable-dial-able-in-able-from-the-faceplate-able
capacitive loading for all three of the MM & MC inputs 0 to 1100 picofarads
in 10 picofarad steps. This is a
tweak-o-holic tube-lover's dream....
- Tube Compliment: - 2 x 6922 plus 4 x 7044
- selectable gain 50, 55, 60, 65dB
- 2 x MC and 1 x MM selectable inputs
- output impedance is only 67 ohms

The
Control Master Preamplifier Manley
offers the CONTROL MASTER PREAMPLIFIER in two versions: LINE only or with PHONO
(MM & MC). The design is completely DUAL-MONO with separate power supplies
for each channel including two custom designed power transformers. The audio
boards are also separate. All the wiring from the rear input connectors to the
front selector switch and precision custom stepped attenuator is painstakingly
hand wired using professional studio twisted pair shielded six-9's copper cable
for optimum shielding and low noise characteristics, and although it would be
much cheaper, easier, and faster to simply put these leads on several feet of
printed circuit board traces like most

The 300B Preamplifer
Manley's most esoteric product is THE 300B
PREAMPLlFIER, is the first and
only preamp to feature these classic tubes. Here is where the impedances are not
too low and the power requirements are not too high: ideal for this kind
of tube in a single-ended configuration. 
Manley combined the historic 300B with another classic, the large
octal based 6SL7GT, for the input stage- all triodes running in pure
Class A operation. To complement this 'retro' feel, they implemented
vacuum tube rectification (two 5AR4's) and regulation (two OD3's) in the
power supply along with plenty of capacity.
Complementing this lovely and
rich sounding line-driver, we employed the two ideas found in premium
passive preamps: a 24 position gold contact Grayhill switch with
metal-film 1% 1/2 watt resistors for a superior audio attenuator and a
widely separated ceramic switch for input selection.

 The
Reference Preamplifier
The Reference Preamp follows on from the Control Master and is also available in
both LINE ONLY and PHONO versions. What sets this preamplifier apart is the
separate vacuum tube regulated power supply (not shown). In the PHONO version,
ahead of the MM RIAA circuitry, is found our superb 'Floating Symmetrical Mode'
Moving Coil stage, which receives the fragile MC cartridge output as a fully
differential signal offering excellent hum cancellation properties and wide
spatial retrieval abilities. Gain of this stage is adjustable and is ideal for
low impedance and medium to high output MC cartridges. Each of the two channels
is on separate printed circuit boards and suspended on vibration-isolated rubber
mounts.

 100/100 Integrated Amplifier
The
Manley 100 /100 integrated amplifier is the biggest stereo or two-channel model
Manley currently builds on a single chassis employing a common power transformer
but with dual-channel rectification and separate filter / reservoir capacity
banks.
Three inputs are provided (TAPE. CD,
& TUNER) together with a precision stepped volume-control ensuring absolute
channel balance. There is a fourth position marked "AMPLI" which
bypasses the switching and volume-control enabling this unit to be used with a
separate preamplifier.
The Manley 100 / 100 Stereo
Amplifier is a choice in power for a basic high quality "no frills"
stereo system offering easy operation and installation.

POWERS AMPLIFIERS
50 Watts Monoblock
These little gems produce 50 watts
RMS from a quartet of EL84 / 6BQ5 tubes driven by a 6414 dual triode driver and
a 12AT7WA input dual triode. The Ei Yugo EL84 has been one of Manley's very
favorite tubes for many years, extremely long lasting and reliable, and can be
considered the smaller brother of the much beloved EL34: really quick-sounding
both in the bass and especially in the top end. And of course this has a lot to
do with the Manley Output transformer.

 The
Snapper
100 Watt Monoblock
Over three months of prototyping in the Manley Magnetics
department resulted in a brand new output transformer design, a true
19-section incredibly complicated piece. The Snapper will crank out 100
watts at 18 cycles all day long and a full 110 watts from about 40Hz all
the way up to 100KHz. Don't let frequency response specs fool you when
people give you amazing bandwidth measured at... oh, five puny
watts. We're talking full power bandwidth here! Continuous duty - Real
Muscle
- read an online
review of this piece.
Brand new for 2002 Manley Labs has put out yet another
all-tube 100 watt monoblock that features a quartet of EL34's in a fully
differential circuit topology, including the input (12AT7) and driver
(7044) stages. This Snapper can be driven fully balanced all the way
through via the XLR inputs. If you have balanced outputs on your
preamplifier, this amplifier is the first Manley design to really let
you take advantage of your XLR's without additional balancing
input circuitry or input transformers. Very cleverly, the unbalanced
RCA's can alternatively be used in this special topology with equally
impressive results. Biasing is easy
with all measurement points and trimpots located on the top deck and
speaker connection is made with heavy duty WBT binding posts.

 250
Watt Monoblock
Neo-Classic Design
Same great ballsy sound, new chassis
design to fit in those HUGE new transformers! The NEO-Classic 250 is
here!
Tried and true: The Manley 500 and 250
Watt Monoblocks are their most powerful push-pull production-models.
Both the circuit design and the selected componentry have been refined
over years and years of development. Reliability that you can depend
upon combined with musical accuracy and emotional authority is what
these amplifiers promise - and deliver. They are able to switch
operation modes allowing the listener to choose between the sonically
seductive qualities of triode and the more powerful tetrode
configuration.
To avoid a heavy power drain when the
cold amplifier is first switched on, Manley created the
"Soft-Start" mode which also functions as an
"Ever-Warm" position allowing the amplifiers to be always
warmed up for pleasurable listening. Each amplifier only consumes 30
watts of power in Ever-Warm mode. A blinking green LED reminds the user
that the amplifier is in warm-up mode because as all the power supplies
are at half-voltage, the amplifier will still play tunes (albeit
not-so-great-sounding-tunes) when the Ever-Warm mode is engaged.

The 500 Watt Monoblock
Tried and true: The Manley 500 and
250 Watt Monoblocks are Manley's most powerful push-pull production-models. Both
the circuit design and the selected componentry have been refined over years and
years of development. Reliability that you can depend upon combined with musical
accuracy and emotional authority is what these amplifiers promise - and deliver.
They are able to switch operation modes allowing the listener to choose between
the qualities of triode and the more powerful tetrode configuration. The big,
beefy reservoir capacitors are used in the high voltage supplies giving plenty
of instant energy for dynamic performance of transient peaks and bass impact and
weight which often exceeds that of rival solid-state amplifiers.

With
the current resurgence of interest in the "retro" technology and
particularly in single-ended retro technology, the matter of sufficient drive
power for modern loudspeakers becomes a very real problem. Manley decide that
the market needed one 'BIG BOY' single-ended amplifier.
