WELCOME TO JET CITY Thank you for purchasing the Jet City Amplification Jettenuator. This device is commonly known as an attenuator, or load-box, and is de- signed to allow your tube amplifier to operate at a high output level - where it will sound best - but at a significantly reduced room volume.

Little or no high end or muddy low end or loss of clarity Mysterious fluctuations in the amp’s overall volume or no sound Most Jet City Amplification 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.
2. OUT SPEAKER - connect to your speaker cabinet to hear your am- plifier as normal. Jettenuator is a full-load device, so it is not necessary to use this connector in all applications. Note a reduction in output level of approximately -3dB even with the level set at 9 is inherent to the design of Jettenuator.
