Introduction
Thank You for Choosing Orange
Ever since the founding of the company in 1968, Orange has been a pioneering force in the guitar amplification industry. Today, with a team of the world’s finest amplifier engineers, Orange continues to push back the boundaries of conventional valve amplifier design.
Our commitment to craftsmanship and quality control has allowed our amplifiers to stand the test of time, giving their owners as much pleasure now, as the day they were bought. To maintain this level of excellence, each Orange amplifier is put through many rigorous test procedures before leaving the factory.
The warmth, tonal quality and rich harmonics generated by a valve amplifier cannot be reproduced by ‘artificial’ means. Many guitarists have reached the same conclusion: neither the transistor nor the microchip is a true alternative to valve technology.
This manual contains valuable technical and safety information. Please take the time to read this manual as the information may enhance the sound and performance of your amplifier. We are confident that you will be delighted with your new purchase and that it will provide you with many years of enjoyment. You are now a member of the Legendary British Guitar Amplifier Owners Club!
In the interests of product improvement, the contents of this manual may be subject to change without notice.

BEFORE USING YOUR AMPLIFIER
Always ensure the amp's volume control(s) are set to zero before switching on the power to amplifier.
To prevent hum and electrical noise operate your amplifier and instruments as far away from other electronic devices (especially fluorescent and neon lamps) as possible as these generate extremely high levels of electronic noise.

Note: Always ensure the amp's volume control(s) are set to zero before switching on the power to amplifier. To prevent hum and electrical noise, operate your amplifier and instruments as far away from other electronic devices (especially fluorescent and neon lamps) as possible, as these generate extremely high levels of electronic noise.
SPEAKER OUTPUT CONNECTIONS (HEADS and COMBOS)
Make sure the correct speaker load is connected at all times during operation.
- Do not connect to a speaker load which is less than 8 Ohms in total!
- Always connect to a cabinet of an appropriate power rating/handling!
- Never use two cabinets of different/mismatched impedance!
- Only connect speakers using a quality dedicated speaker cable. Never use an instrument cable!
- Never connect headphones to the speaker outputs!
- 1 x 16 Ohm cabinet – Use the 16 Ohm speaker jack socket (rear of chassis).
- 2 x 16 Ohm cabinets – Use both of the 8 Ohm speaker jack sockets (rear of chassis).
- 1 x 8 Ohm cabinet – Use either of the 8 Ohm speaker jack sockets (rear of chassis).
If you are unsure, please contact your Orange Dealer.
Only connect speaker cabinets in accordance with this manual. Failure to do so will cause damage to the amplifier and void any warranty:
Heads:
Combos:
All Orange valve combos have an internal speaker load of 16 Ohms and are connected to the amplifier's 16 Ohm output at the factory. When using an extension cabinet, only ever connect a 16 Ohm cabinet!
To connect an extension cabinet to the combo reconnect the internal speaker jack to either of the 8 Ohm speaker outputs, and connect a 16 Ohm extension cabinet to the other 8 Ohm speaker output.
Be sure to reconnect the internal speaker to the 16 Ohm output when an extension cabinet is not attached.
VALVES:
When powering up, ensure the amplifier is set to the STBY position on the front panel for a minimum of two minutes prior to performance. This will prolong the life of the valves.
The HT Fuse(s) (rear of chassis) will blow in the event of output valve failure in order to protect the internal circuitry from damage. Orange recommends output valves are replaced in full matched sets. Orange models fitted with EL34 or 6550 valves will also benefit from a bias adjustment which should only be undertaken by a qualified technician. When changing the HT fuse, gently push down on the fuse holder and turn anticlockwise to release the fuse.

VALVES AND FUSES CAN FAIL AT ANY TIME!
From time to time output and preamp valves may fail. For optimum performance, we recommend output valves are renewed at least once a year. All Class A/B models (50 Watts and above) will benefit from having the bias checked and adjusted when output valves are changed. This should only be carried out by a qualified engineer.
Orange amps are protected from damage caused by valve failure and inconsistent mains voltage by various fuses. We recommend that Orange users have a set of spare valves and fuses.
