So you want your Mackie, Ampeg, Crate or Tapco product upgraded?
You’ve come to the right place

For many years Surrey Amps has been the principal UK service and technical support centre for Loud Technologies products (Ampeg, Mackie, Crate, Tapco and EAW).
Not only do we repair units but where possible improve and upgrade, we often get called to support a lot of the older sought after units too,
such as the Mackie SA1530z or SR1521.
Where possible we are able to source original RCF drivers, when parts are no longer available we can remanufacture, such as rewind transformers or recone speakers. Every unit that we repair goes through the same rigorous attention to detail and comes with it’s own test report.
To see how we can make your unit sound at least as good as new, use the navigation menu at the top of this page to find out more.

What Client’s Say

“I doubt anyone but Surrey Amps could have chased down this fault with such determination. I will never go anywhere else for my servicing and repairs.”
Jim Cregan, Guitarist - Writer - Producer
“Although I have been pleased with my Ampeg product, the reason that I would buy Ampeg again would be knowing that I had Surrey Amps behind that product if I were to run into problems again.”
John Pawsey, Ampeg Heritage SVT-CL
“SurreyAmps have called back when promised, always been available, courteous and been able to provide technical feedback at the right level to resolve my issue. Truly outstanding customer service!!!”
Howard Pelling, Mackie SRM1801

See what else we can do

When replacement speakers become discontinued the only option would be to have the old speaker rebuilt. As long as the magnet is not damaged and the basket is not twisted then this can sometimes be a cheaper alternative than buying new. We use OEM recone kits supplied directly from the manufacturer. Where this is not possible we have teamed up with Celestion who can offer replacement speakers as close to the original specifications as possible. These are generally a far superior replacement than the original speakers. For more information click here.
Not only used in vintage amplifers, a lot of smaller NEW amps/speakers use a toroidal transformer. Sometimes it can be hard to find a replacement, this is where a new transformer can be rewound. Even when the specs aren’t available the transformer can be reverse engineered and made to the exact same specification. If your interested in having a tranformer remanufactured then use the contact form here, alternatively you can find more information on the Surrey Amps site.
Why not bring some new life into your old amplifer? We specialise in restorations of older valve amplifers. From a simple re-valve including re-biasing to a complete rebuild including fitting new tolex. If neccessary we can also rebuild the complete cabinet. Why not get in touch to discuss your requirements.
