About the Service
Can you provide an estimate before I send my amplifier?For many common faults, I can often provide an approximate estimate based on the model and symptoms you describe. A confirmed quotation, however, can only be given after proper diagnosis.Can you repair my amplifier while I wait?Unfortunately not.
Even when the fault appears straightforward, proper diagnosis, repair and testing take time. Every amplifier is individually assessed and thoroughly tested before being returned, and this process cannot be completed while you wait.
My priority is to carry out a reliable repair rather than the quickest possible one.
Do you repair Hi-Fi and Professional Audio amplifiers?Yes. In addition to the specialist subwoofer amplifiers featured on this website, I also repair Hi-Fi and Professional Audio (PA) amplifiers.
If you would like advice regarding a particular unit, please feel free to contact me.
Do you repair models not listed on the website?Yes. I also repair many other audio amplifiers and subwoofer amplifier modules.
If you’re unsure whether your equipment can be repaired, please get in touch. I’m always happy to offer advice and an initial assessment.
General Advice
Can I contact you for advice even if I haven’t decided to proceed with a repair?Absolutely. I’m always happy to offer advice where I can. Even if you haven’t yet decided whether to send your amplifier, please feel free to get in touch.
Pricing & Payment
What payment methods do you accept?Payment is currently accepted by bank transfer.
When do I pay?There is no upfront payment for repair work. Once your amplifier has been repaired and successfully tested, I will contact you to confirm completion and provide payment details.
The only exception may be repairs that require expensive parts to be specially ordered specifically for your amplifier. In such cases, I may request a partial payment to cover the cost of those parts before proceeding. This will always be discussed and agreed with you in advance.
Repairs & Upgrades
Can you improve the reliability of my amplifier?Yes! Over time, certain amplifier models have proven to have recurring weaknesses or age-related issues. Where appropriate, I may recommend preventative improvements based on experience to help enhance long-term reliability. Any such work will always be discussed with you beforehand.
Do you repair at component level or replace the entire amplifier module?Component-level repair is the primary approach and forms the basis of the service I provide. In most cases, faults can be diagnosed and repaired by replacing only the defective components, preserving the original amplifier and often resulting in a more economical solution.
Complete amplifier module replacement is only recommended where it is genuinely the better technical or financial option—for example, where damage is too extensive, suitable replacement modules are readily available at sensible cost, or component-level repair would not represent good value.
Every amplifier is assessed individually, and my aim is always to recommend the solution that offers the best balance of reliability and cost-effectiveness for the customer, rather than simply the quickest repair.
Do you use genuine replacement parts?Where genuine components are available and appropriate, they are used. If original parts are obsolete, carefully selected high-quality equivalents are used that meet or exceed the required specifications. Every part I use is sourced only from top-tier components distributors.
How long will my repair take?Turnaround depends on the nature of the fault, workload and parts availability. Every amplifier is individually diagnosed, repaired and thoroughly tested, so repair times naturally vary. My priority is quality and reliability rather than the shortest possible turnaround.
What if my amplifier cannot be repaired?Although the vast majority of amplifiers can be successfully repaired, this cannot be guaranteed in every case. If repair proves technically impossible or economically unjustified, I will explain the reasons and discuss the available options.
No payment is required if a repair cannot be completed. You may then arrange collection or return of your amplifier, or, if preferred, I can dispose of it responsibly on your behalf.
Return Shipping
Can you arrange return shipping for me?
While I can arrange return shipping if absolutely necessary, I strongly recommend that customers book their own courier collection.
The reason is simple: the amplifier is your property, and the person who books the shipment is generally the party entitled to deal directly with the courier in the event of loss or damage and to make any associated insurance claim. If I book the service on your behalf, resolving such issues can become unnecessarily complicated for both of us.
By arranging your own courier, you remain in full control of the shipment, the insurance and any claim process should it ever be required. In my experience, this is the safest and most straightforward approach, which is why it is my preferred method for returning repaired equipment.
Is return shipping included in the repair cost?I do not include or charge for return shipping as part of the repair service. The reason for this is closely related to the answer to the next question, “Can you arrange return shipping?”, which explains why I generally recommend that customers arrange their own courier collection.
Sending Your Amplifier
Can I deliver my amplifier in person?Certainly. Collection and drop-off can be arranged by prior appointment. Please contact me to arrange a convenient time.
Do I need to send the entire subwoofer?In most cases, only the amplifier module needs to be sent, rather than the complete subwoofer. This significantly reduces shipping costs and minimises the risk of transport damage.
Removal instructions are available on this website for many of the most common models. If your model is not listed, or you are unsure how to remove the amplifier safely, please get in touch. I’m always happy to provide further advice and guidance before you send your equipment.
How should I package my amplifier?Please use a strong box with generous protective packaging so that the amplifier cannot move during transit. Damage caused by inadequate packaging can often be avoided with careful preparation. If in doubt, feel free to ask for guidance. I’ve also included some packaging ideas and examples on this page here.
Which courier service do you recommend?Recommended courier services and shipping advice can be found on the Courier Information page.
Spare Parts
Do you sell spare parts?From time to time I offer genuine and hard-to-find spare parts for KEF, Celestion and other audio equipment. If the part you require is not listed on the Spares page, please get in touch—I may have it available or be able to help source a suitable replacement.
Warranty
Do you provide a warranty on repairs?Yes. All amplifier repairs are covered by a 12-month limited warranty against recurrence of the same fault, covering the work carried out and the components replaced.
Unfortunately not.
