How we work and why you should choose us.

Going the extra mile to ensure a thorough repair is one of the many differences between The Amp Doctor and some other service organisations. With over 22 years experience of reference amplifier design, engineering, construction and upgrades and a sterling reputation in the industry, our services are used by audio dealers and retail customers worldwide.

We provide a 12 month warranty*, not just on the parts we fit but also the functioning of the whole amp. This gives you peace of mind that the amp will function reliably for at least the next 12 months and likely well beyond this. * 3 months warranty for SPL amplifiers.

Our guiding philosophy is to carry out any work to your amplifier in a thorough and comprehensive way that will ensure it serves you reliably, or in other words, do it right the first time. Our warranty is your assurance that we will do this, but if for some reason the amp fails within this period then we will repair it for you free of charge.

The repair procedure consists of repairing the fault, followed by a general service and test of the amplifier.

Repairs often need to be quoted once the amplifier has been received as the damage can vary significantly depending on how and when it was caused.

In order for us to know that the amplifier will be totally reliable for the duration of the warranty, and beyond, we need to find out why the amplifier failed in the first place, and then take steps to prevent this happening again.

A good example of this thorough approach:

Many amplifiers are built in such a way that the connecting wires (leads) of the power devices are mechanically fractured by vibration of the circuit board. We secure the circuit board with a damping compound to prevent it vibrating and then ensure all remaining devices have secure leads, replacing any that have fractures. This is a preventative measure to prevent the leads from breaking on any of the power devices in the future, thus significantly enhancing the long term reliability of your amp.

Please be advised that we cannot accept any amplifiers over 4000 Watts without prior arrangement. We are happy to talk to you about any larger amplifiers and advise if we are able to help.
