A Message from Genesis

The Genesis Integrated 60-Watt Valve (or vacuum tube) Amplifier is a
limited-edition product that was created as proof of concept that a well­designed, well-executed, value-priced amplifier will be able to drive any
Genesis loudspeaker with ease and authority.

The transparency, detail retrieval, dynamics, and wide frequency extension
of Genesis loudspeakers place great demands on the quality of
amplification. Because of our emphasis on absolute fidelity™ above all else,
the speakers do represent a difficult, but not impossible load for an amplifier
to drive. The I60 was created as a partner to a pair of Genesis loudspeakers,
and as a result, it has the quality of amplifiers costing much more.

The I60, together with a pair of Genesis loudspeakers, will give your entire
music collection a whole new life. In a well set-up system, it is capable of
transporting the musical performance into your room. The hiss and hum
normally associated with vacuum tubes are completely absent, while
retaining the richness and rightness of the best of this genre of amplifiers.

While developing a value-priced product, quality has not been scaled down.
Hand-selected, precisely matched components are used throughout:
custom-made military-spec paper-in-oil capacitors with aluminum cans are
selectively used; tantalum-film resistors are used on a hand-built discrete
resistor potentiometer as a volume control. The output transformers and
power transformer are laboriously hand wound to precise specifications
tailored to the circuit and tubes used. Point-to-point wiring using solid-core
silver wire is used in the entire signal path. This reduces the resistance,
capacitance and inductance normally associated with ordinary printed circuit
boards. Each and every unit is first burned-in on the test bench, and then run
in for over 100 hours before final test and packaging.

Very little feedback is used – just enough to make the amplifier
unconditionally stable. Not the excessive amount usually employed to make
amplifiers measure better at the expense of musicality. The result of all this
obsessive attention to detail is a fabulously musical amplifier capable of
driving almost any loudspeaker in the world.

Before using this unit, please take the time to carefully review the safety
instructions and operating information contained in this Owner’s Manual and
Set-up Guide. Becoming familiar with your new amplifier and the correct
operating procedures will help assure you of safe usage, reliable operation,
and maximum musical enjoyment.

Set-up and Safety Information

Now that you have your new amplifier, we realize that you can't wait to hook
it up and start playing! However, please read this set-up guide and safety
information before you proceed.

Unpacking and Setting Up

Your amplifier is heavy, and its vacuum tubes are delicate and dissipate a
great amount of heat. It is important that this product is never used near
water or sources or water. Avoid bathrooms, washbowls, kitchen sinks,
swimming pools, etc. Damp basements should also be avoided.

Get the help of a friend, because these amplifiers are HEAVY. Carefully
remove the amplifier package from the carton and unwrap it. Place it on a
solid, level surface with adequate ventilation. It should not be placed in a
built-in installation or rack unless adequate proper ventilation is provided. Do
not place your amplifier in a closed bookcase or cabinet. Never obstruct the
top part of the amplifier with any objects that could result in the valves
overheating.

The amplifier should not be subject to vibration of any sort. Do not place
them directly in front of, or on top of your loudspeakers. As valve amplifiers
can be microphonic, vibration of the tubes will distort the signal.

Next, carefully remove the tube cage by carefully lifting it vertically upwards.
Remove the protective foam around the individual vacuum tubes, and
replace the tube cage. This protects the tubes from damage, and also
protects inquisitive fingers from the hot tubes!

Before you plug the power cord in, please make sure that you have the
model with the proper voltage for the country you are in. Taiwan, Japan

and North America will require the 115V version. Most European countries
and other Asian countries will require the 230V version. We have found that
a single voltage power transformer sounds better, and hence the amplifier is
designed for a single-voltage only.

Safety Information

1. Never try to disassemble the amplifier as you may be exposed
to dangerous voltages. Vacuum tube amplifiers operate at
hundreds of volts. Even after turning the amplifier off and
unplugging it from the wall socket, it will retain a lethal electrical
charge for some time.

2. Do not attempt to modify the amplifier. The device has been
tested and adjusted for optimal operation and should give you

I60 Owner’s Manual Ver 1.2

3

years of trouble-free service. Please see Adjusting the Bias and
Replacing Tubes (pages 9 and 10) for special instructions.

3. Vacuum tubes dissipate a large amount of heat and will result in
very high temperatures:
a. Do not touch the tubes with bare hands during, and

immediately after operation. It could cause severe burns.

b. The I60 features a removable “tube cage”. However, we

recommend that for the sake of safety, you operate the unit

with the tube cage left in place.
c. Do not leave the device within the reach of children.
d. Vacuum tubes are made of glass, and hot tubes will shatter

if a single drop of water lands on it! Care must be taken so

that objects do not fall into, and liquids are not spilled into

the unit.
e. Do not expose the tubes to moisture.
f. Do not attempt to clean the device with a wet cloth, or any

solvents or cleaning solutions.

4. The vacuum tube amplifiers are fragile instruments. Do not
subject the unit to excessive shock, smoke, dust, or mechanical
vibration.

5. Do not move the amplifier while the tubes are still hot. Allow the
amplifier to cool down first before attempting to relocate the
amplifier or to change the tubes.

6. Do not connect or disconnect the loudspeakers from the
amplifier while it is playing. Turn the amplifier off, and wait a
couple of minutes before making any connections. Before
turning the amplifier on, it should be properly connected.

7. Do not run the amplifier without the appropriate
loudspeakers connected to it.

8. This device should be operated at a maximum of 5A current. Do
not replace the internal fuse with one rated higher than 5A.
