Since 1968 when the company was founded, 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 procedu res
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 th e transistor nor
microchip is a suitable alternative to valve technology.
This booklet 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.

HOW DOES THE ORANGE VT1000DIFFER FROM OTHER
COMMERCIALLY AVAILABLE VALVE TESTERS?
Commercial valve testers have been available, almost since valves were invented, incorporating
many excellent techniques and designs over the years. However, the vast majority have a number of
common features, which we considered to be a barrier to the modern valve user namely:
They require a certain level of user interaction in that parameters have to be set for
individual valves being tested.
They require a certain depth of knowledge about valve theory, which some users may not
have.
The results obtained on meters or digital readouts require a certain level of user
interpretation.
They are often quite large and bulky.
In a lot of cases, they are also not very portable and since most are mains operated, require
selection of mains voltage if required to be used in other than their native country. When developing
the VT1000 we decided to ‘break the mould’ to produce a fully automatic valve tester, which
performs a wide range of tests quickly and accurately.
Requiring little or no knowledge of valve theory, it can be operated by experienced users and those
who just want to know that the valves in their amplifier are in good condition. It requires no user
interaction other than inserting the valve to be tested into the correct socket, selecting the type
from a list using two up/down buttons using an LED bar display, then finally pressing an ‘OK’ button
to start the test.
