Excellent service and kept informed throughout the process. Was initially concerned as I thought I was dealing with a local company where I could have … More dropped my DVD player in for repair only then to find out I had to post it via the Royal Mail service. All postal requirements were sent over and in the event the service was quick and painless and given notification of its safe arrival. As the DVD player sound surround system was around 20yrs old I was surprised that Electronic Partners were able to undertake a repair and give us many more years service of our system meaning no wastage of all the other perfectly good parts such as the speakers. EP also met my need in delaying the return postage until a time that I was able to be at home to receive the DVD player. Would definitely recommend EP and would use again where one can repair and reuse perfectly good equipment rather than unnecessarily throw it away. Many thanks EP. -
Brilliant service! Communication was top notch, cost was competitive and I would definitely use again! So pleased to have my ancient Sony system working … More again!

They provided a first class service in repairing our Bose CD player at a reasonable price. Everything went well in a very timely fashion- collection, repair … More estimate, repair itself and delivery back. CD player back home and playing like new. Service at its best. If I could give them 6 stars I would!
We provide a professional alternative to manufacturer service centres, specialising in out-of-warranty restoration and complex circuit failures that others deem “unrepairable.”

Precision Audio Engineering & Restoration
High-end audio equipment requires a deep understanding of both digital logic and analogue signal paths. Our technicians utilise oscilloscope analysis and precision soldering to identify noise floor issues, signal distortion, and power stage failures.
⚡ Power Stage Repair
We resolve “no power” issues, blown transformers, and failing capacitors in both solid-state and valve-based amplification systems.
🎶 Signal Path Optimisation
Elimination of crackling, channel imbalance, and audio dropouts through precision cleaning of potentiometers and replacement of degraded components.
🔍 Component-Level Rework
Instead of replacing entire boards, we identify and replace specific failed transistors, resistors, or ICs to maintain the original sound signature.
Audio & Hi-Fi Brands We Commonly Repair
Our technicians regularly repair and restore audio equipment from leading hi-fi manufacturers. We specialise in out-of-warranty support for legacy and modern high-end systems.
- Marantz
- Naim
- Cambridge Audio
- NAD
- Pioneer
- Yamaha
- Denon
- Rotel
- Arcam
- Quad
- Bowers & Wilkins
This list is not exhaustive. We assess repairability based on circuit design, component availability (including obsolete part sourcing for vintage units), and economic viability.
Common Hi-Fi Failure Vectors
Audio equipment often suffers from age-related component degradation or mechanical wear in moving parts:
📉 Capacitor Degradation (Recapping)
Electrolytic capacitors have a finite lifespan. We perform full or partial “recapping” to restore bass response and system stability in vintage units.
📻 Digital & Logic Failures
Modern Hi-Fi units often suffer from failed firmware chips or HDMI/Optical port damage. We perform BGA rework and port replacements on digital receivers.
View Mechanical & Optical Faults (CD/Turntable)
💿 Optical Drive Repair
We resolve “No Disc” errors and tray malfunctions in high-end CD players and transports through laser calibration or replacement.
🔌 Connectivity Issues
Repair of dry solder joints on RCA inputs, speaker terminals, and headphone jacks that cause intermittent audio loss.
The Case for Audio Restoration
✅ Why Repair Audio Gear?
- Acoustic Character: Vintage gear often possesses a “warmth” that modern Class-D amplifiers cannot replicate.
- Build Quality: High-end legacy equipment was built to be serviced, featuring heavy-duty transformers and discrete circuits.
- Sustainability: Preserving high-quality hardware reduces electronic waste and maintains the value of your collection.
❌ When to Reconsider
- Entry-Level Modern Gear: Budget “all-in-one” systems where the cost of labour exceeds the replacement price.
- Proprietary Digital Failure: When a modern unit has a failed proprietary processor that is no longer manufactured.
- Severe Physical Damage: Cracked PCB mainboards or catastrophic fire damage to internal looms.
Service Logistics & Frequently Asked Questions
The Audio Repair Pathway
Do you repair vintage valve amplifiers?
Yes, we have extensive experience with valve (tube) technology, including bias adjustment and sourcing high-quality replacement valves.
Can you fix “crackling” volume knobs?
In most cases, yes. This is usually caused by oxidation in the potentiometers. We perform deep ultrasonic cleaning or replace the component if the track is worn.
How do I ship heavy audio equipment safely?
We recommend double-boxing with at least 2 inches of padding. For very heavy amplifiers, we can advise on specialist courier requirements during the estimate process.
