OWNER’S MANUAL
WELCOME TO JET CITY
Thank you for purchasing the Jet City Amplication Jettenuator. This
device is commonly known as an attenuator, or load-box, and is de-
signed to allow your tube amplier to operate at a high output level where it will sound best - but at a signicantly reduced room volume.
Jettenuator can be used effectively in rehearsal, live performance, and
recording environments, to deliver great tones in situations where loud
volume is not desired. And the inclusion of our MicSim circuit adds the
convenience of a speaker-like output without the need of a speaker
cabinet or microphone. Think of it as being able to plug your tube head
directly into a mixing board with a sound like a live-room mic’d up amp.
DANGER: RISK OF ELECTRIC SHOCK, DO NOT OPEN

CAUTION: To reduce the risk of electric shock, do not remove
cover or open rear panel. No user serviceable parts inside: refer
handling to qualied personnel. To reduce the risk of re or electric shock, do not expose this product to rain or moisture.
Uninsulated dangerous voltage may be present inside the enclosure – voltage that may be sufcient to constitute a risk of shock.
Changing your amplier tubes is safe, after allowing them to cool.
There is no set timeline for changing tubes. If you play every day,
a good rule of thumb is to replace your power tubes once a year
and your preamp tubes every other year. However, it is entirely
possible for tubes, particularly preamp tubes, to last decades.
Here are some signs that you need to change your tubes:
Excessive noise like squealing, humming, or hiss
Little or no high end or muddy low end or loss of clarity
Mysterious uctuations in the amp’s overall volume or no sound
Most Jet City Amplication tube amps operate on a Fixed-bias,
which allows you to change both preamp and power tubes of the
same type without needing a bias adjustment. Fine adjustment to
the bias is possible, but only by a qualied service technician.
