We specialise in bringing back your once loved pieces of hi-fi audio equipment to life! We are especially versed in refurbishment of original Cyrus One and Two amplifiers.

Full restorations of equipment that need some much needed TLC, repairs where things have gone wrong, and modifications for when things could be just that little better!

We have a passion for hi-fi separates from years gone by. These things were often built to last, and even if time has taken it's toll, the designers of yore often worked in to their equipment the potential for a new lease of life when the time comes.

But don't think that 'Vintage' means 1940s valve radiograms! We love giving a new lease of life to solid-state amplifiers from the 1970s and 1980s and over the last few years we've done a lot of work for owners of Cyrus One and Two amplifiers, offering a complete refurbishment package along with repairs and upgrades at very reasonable prices. And each one of customers have been nothing but happy by the work carried out on their units!

Some of the testimonials from customers that used our services:

"All I can say it was worth the wait: what a revelation! I feel I must have been listen to aural mud for the last few years. Everything is so much clearer - instruments can be heard in their proper place left and right and singers are distinct from the orchestra. All the sounds seem to have much more depth and 'space' around them - it was like being in the concert hall! Just wonderful.
So a huge thank you for all your work. I am most grateful and anticipate with great joy getting to know my library of recorded music fully once again.
With all best wishes,
B. Jackson"

"It's arrived! Glorious sound, you have every right to feel proud of your work. Further comment seems unnecessary,
Regards, a very happy man,
E. Clark"

"Many thanks to you! We received the amplifier today, it sounds really great! Now I am searching for new sources to get the full potential from the amplifier, it is that good.
Kind regards,
K. Brandscheid"

"On first hearing, all sounding fantastic - unbelievable clarity which is almost unsettling at times. Have tried all inputs and all working great thanks. I am sure the amp will get even better as it settles in but I am so pleased for everything that you have done. You are a real star! Let me know if you want a testimonial for your eBay description.
All the best for now,
I. Brindley"

"It arrived this morning and is working beautifully, thank you very much! Really appreciate your service.
Best wishes

We have just repaired a NAD C315BEE integrated amplifier that was sent to us. It was the first time we've worked on this model, the fault was loud buzzing whether or not there is audio playing. It's quite well known that the main power supply reservoir capacitors go faulty and here is part of the reason why.
Rather than spending a few pennies more on what is crucially important parts, NAD chose to use parts barely rated to do their job, far too close to their working voltage and also sourced from a known terrible capacitor manufacturer (Samxon). With those two capacitors replaced the amplifier now works again, buzz free and with uprated parts for hopeful longevity. We were stunned to find the two original parts had blown their tops and leaked electrolyte from both ends of the capacitors. The legs on one of the capacitors had disconnected from the capacitor and it had almost disintegrated, we've never seen anything quite as bad in the capacitor department!
The attached photo is from the schematics for this amplifiers where NAD rather unbelievably tell users to uprate the components themselves because they cheaped out on part sourcing!
