INTRODUCING THE H-1201 PHONO STAGE
The H-1201 is Allnic Audio’s entry level phono stage
model. Like all Allnic Audio products, it uses Permalloy
(iron and nickel alloy) for its transformer cores. Allnic is
grateful to Mr. G.W. Elmen of Western Electric for
inventing Permalloy for transformer core use, and in so
doing, providing an enormous service to recorded
music listeners everywhere.
The H-1201 has the following features:
High-quality, NOS E180CC twin triode tubes
CR type RIAA equalization, precisely compensated
within +/- 0.3dB
Automatic, semi-conductor voltage regulation
circuit, ensuring exceptionally quiet operation
High quality Moving Coil Step-up Transformers
with Permalloy cores
MC transformers variable gain (+22dB, +26dB,
+28dB and +32dB)
No negative feedback design
Pure Class A operation
New vacuum tube damping technology – Allnic
Audio’s patented "Absorb GEL tube damper"
technology prevents harmful vibrations from
reaching the signal / gain tubes and, therefore,
prevents micro-phonic noise propagation in the
tubes. The Allnic Audio Absorb Gel damper
technology effectively solves a problem that
plagues most tube amplification systems. Provided
other tube components do not introduce micro-
phonic noise into your system, with the Absorb Gel
damping system, you will enjoy a degree of
transparent sound that will surprise and please
you.
As are all Allnic Audio products, the H-1201 is fully
RoHS (EU Reduction of Hazardous Substances
regulation) compliant in construction and materials
WHAT’S IN THE BOX?
Please check that the shipping box contains the
following:
One (1) Allnic H-1201 phono stage – in natural
aluminum or black, depending on your order request
One (1) IEC type power cord
One (1) Owner’s Manual
Note:
1) The H-1201 ships with the tubes installed.
2) The H-1201 will work with most IEC type
aftermarket power cords. Of course, only you can
determine the power cord that works most
synergistically with the H-1201 in your system.
3) Be sure the H-1201 is labeled for the AC voltage of
your location. If it is not, please contact
Hammertone Audio (See Figure 1).
We advise that you keep the box and other packing
materials that your H-1201 came in. It will be useful if you
sell your H-1201 or in the unlikely event you need to ship it
for service.
SAFETY
Remove ALL protective cushioning material inside
the tube chimneys before operation. The tube
chimneys should contain NOTHING except the
tubes. You may experiment with the tube damping
rings, on or off.
Disconnect the power cord by pulling the plug, not
the cable.
Do not attempt any repairs. Do not remove the
unit’s chassis covers without specific authorization
from Hammertone Audio.
Keep the power cord away from heat sources
Keep the unit away from liquids – do not allow any
liquid to enter the interior of the unit.
When the unit is moved from a cold to a warm
environment, allow sufficient time for any condensation
to evaporate before plugging the H-1201 into an AC
connection.
See the notes on “Location, Location, Location”.
CLEANING
A. Chassis
Use only a soft, lint-free cloth dampened slightly with water
only (NO cleaning fluids!) to clean the faceplate and chassis of
the H-1201 and its power supply.
B. Connectors
You may use any good quality contact cleaner recommended

5
for such applications to clean the contacts from time to
time, as you deem appropriate.
INITIAL SET-UP
A. LOCATION, LOCATION, LOCATION
Like all audio products using tubes, the Allnic Audio H-1201
needs to be placed on a solid stand in a location that provides
good air circulation around the phono stage.
DO NOT cover the top of the H-1201 phono stage or
tube chimneys.
DO NOT place the unit on carpet or foam.
DO NOT subject the unit to knocks and shocks as you
move it around. This advice is meant particularly for
those who may want to place the H-1201 on some
kind of after-market isolation feet or similar devices.
Dropping the H-1201 is not a good thing to do and
may void the warranty.
DO NOT place the unit near a strong light or heat.
DO NOT place anything heavy on the unit.
DO NOT allow rubber or vinyl materials to rest on the
unit’s chassis for long periods of time. This could
discolour the metal.
DO place the unit on a shelf or stand that is stable
and not subject to vibration or sudden shock.
DO consider using a high quality power cord and
inter-connects, for both inputs and outputs. The H-
1201 is a highly sensitive piece of electronic designed
for neutrality and will output what you put into it.
DO try to place the H-1201 away from major sources
of RFI and EMI; though well shielded, the H-1201 will
function best away from large power transformers
and other sources of such interference.
B. POWER CONNECTIONS
The H-1201 uses a standard three prong male IEC
connection for AC input. You need to use a power cord with
a female three prong IEC connector at one end (See Figure
1).
The H-1201 power supply you have purchased is set
internally for AC 110/120 volt – 60 HZ operation. There is no
way to change this to another AC setting without return of
the unit to the factory for re-wiring, at the owner’s cost,
including transport both directions.
C. INPUTS
There are two (2) pairs of single-ended (RCA) inputs, one for
Moving Coil (MC) cartridges and the other for Moving Magnet
(MM) cartridges. These two pairs are located in the middle of
the rear of the H-1201 (See Figure 1) and labeled “MC – input –
MM” between the top and bottom connectors. Facing the rear
of the H-1201, the left hand pair of inputs is the moving coil
cartridge input; the right is for moving magnet cartridges. Each
pair of inputs is aligned vertically, with the left channel “left”
labeled input at the top and the “right” labeled input on the
bottom.
To the left and right (facing the rear panel) of the MC and
MM input connections respectively is a screw type ground
connector. Either or both of these may be used for multiple
ground connections.
When you are facing the front of the H-1201, the input
connections are in the centre of the unit, with the MC
connections on the right and the MM connections immediately
to their left.
The H-1201 has been designed and manufactured to work most
synergistically with Allnic Audio preamplifiers, pre-phono stages
and equalization products.
D. OUTPUTS
The H-1201 is equipped with one set of unbalanced or “single-
ended” (RCA) outputs The output connection is just to the left
(facing the rear panel) of the AC IEC power cord connection. The
left channel output connection is the top one and is labeled
“left”; the bottom, “right” (See Figure 1).
E. Moving Coil (MC) Transformer Controls
On the top of each channel’s MC transformer on the centre
rear of the chassis deck of the H-1201 (See Figure 4), there is
a rotating control (See Figure 3). Turn the control knob to
select from four gain factors: +22dB, +26dB, +28dB and
+32dB. Combined with the H1201's 40dB native gain, for MC
there is 62dB, 66dB, 68dB and 72dB of gain available.Each of
the second set of indicators on the top of the transformers
only marks the impedance tied to the gain setting diagonal
