Welcome to the updated & improved SynthRestore website! We are constantly seeking to improve our services & the products we offer. Alongside our analogue synth spares, we still offer repairs and servicing to your vintage analogue synthesizers & related equipment. We have recently added a secondand synths for sale page.

The AR-57 Aurora synthesizer is our very own creation (manufactured under the name of Harpur Instruments). It is not licenced to be sold by any other retailer.

Each AR-57 synth is hand-built and tested on-site, making it a truly British made product. UK price £1295

KEY FEATURES include: 3 analogue oscillators, 2 sub oscillators, LFO (tri, saw, square, random). Plus a unique 'pattern' waveform. Circuits utilize Military-spec. components. Full details of functions and audio demo's here.
