TUBE CLOCK-MANUAL 1.0

Hughes & Kettner’s legendary Custom Class amplifiers
TriAmp, Duotone and Puretone are among the world’s
most demanded tube amplifiers. Their outstanding tone
and unique visual design instantly cast their spell upon
guitarists and tube-purists alike. The Tube Clock™ now
transports the classic glow and fascination of tube
products right into your shops, onto your desk, or into
your living room. With every second passing, this unique
design object will give you a totally new sense of time!

The Design

With Tube Clock, you will enjoy every moment of time
passing - perhaps for the first time. The blue-lit, transparent
front allows you to see the lavishly chrome-plated chassis
with time being displayed by six mysteriously glowing tubes.
The true-to-style Tolex covering and the solid brass chrome­plated “Dome Speed Knobs”, mirror the awesome look and
feel of Hughes & Kettner’s tube amplifiers.

Magical Glow

Half a century ago, the legendary Nixie valves were the very
definition of high-tech, and they still hold on to their special
charm to this day. Their magic glow puts an end to those
cold and boring digital seconds. The numbers punched into
the tubes’ heating grids turn time into glowing metal and
bring back warm memories of classic 60’s movies such as
“James Bond – Goldfinger” instead!

Limited Time

Nixie tubes have been out of production for a long time
already, but we were able to secure remaining contingents
from Russian military stocks. Due to the limited availability of
this extraordinary type of tube, our Tube Clock will only be
available for a short period – turning it into a true collector’s
item from day one!

A New Sense of Time

Don’t let time slip away. Don’t miss your chance to “tubefy”
your time – the fascination of classic tube design will make
you feel the pulse of Rock’n’Roll every moment of your day!

Tube Clock - Time that really rocks!

Operation

Before using for the first time

• The Tube Clock has a built-in wide-range power unit and
can be used all over the world. From the mains cables
supplied, please select the suitable cable for the mains
socket usual in your country.

• Before connecting the Tube Clock to the electricity mains,
make sure that the two toggle switches POWER and
STANDBY are pulled down (off), that the two knobs TUBES
and PANEL are in the middle position, and that the MODE
knob is set at either 12 H or 24 H.

• Ensure that air can flow freely through the cooling slits of
the device.

• Make sure that the device is placed on a stable, even
surface in a place that rules out external mechanical and
thermal influences that could jeopardise the reliable
operation of the device or the safety of people.

• The manufacturer accepts no liability for damage to the
device occurring due to incorrect operation.

N.B.: The internal clock of the Tube Clock is supplied with
electricity even when switched off. The Tube Clock cannot be
separated from the electricity mains by using the POWER
switch. To do this, it is always necessary to remove the mains
cable either from the device or from the mains socket! The
internal clock is equipped with a buffer for the eventuality of
a power failure, transportation, or other reasons that make it
necessary to separate the Tube Clock from the electricity
mains for a short period. If the clock is separated from the
mains for a longer period, it must be reset.

POWER Toggle Switch

The clock is switched on using the POWER switch. If you flip
the switch up, the red power LED and the blue panel lighting
lights up.

STANDBY Toggle Switch

As usual with the valve amps, the valves are activated
separately from the POWER switch via the switch STANDBY.
The valves only glow when POWER and STANDBY are
switched on (switches flipped up).

PANEL Knob

With this knob, you can adjust the brightness of the blue
panel-illumination and of the red Power-LED as you wish
from very dark in the position DARK to bright in the position
BRITE.

TUBES Knob

The brightness of the valves is adjusted by the TUBES knob.

PULL TO SET Knob

If you pull out this so-called pull-push poti, the clock stops,
and the seconds display flashes and shows zero. You can now
set the hours using the HOURS knob and the minutes using
the MINUTES knob. Pressing the potis starts the clock running
from the set time. The turning of this poti has no function.

HOURS and MINUTES Knob

After pulling out the PULL TO SET poti, you can set the hours
and minutes using these knobs. The seconds are not set in
this way, but instead begin at zero as soon as the Tube Clock
is started by pressing in the PULL TO SET poti.

MODE

With the MODE knob, you can chose from between a 24­hour and a 12-hour display. The display-mode can be
switched during running operation without activating the
PULL TO SET poti. “PM” is displayed in the 12-hour-mode by
an illuminated point at the bottom right in the second valve
from the left.
