!!!!!!! AURORA AR57...UNITS AVAILABLE.....APRIL 2014

There will be 3 units available from the end of April, light oak cases with a black panel. Please enquire if you are interested.

The Aurora AR57 is the current model in the line of hand built analogue synths from Harpur Instruments (the manufacturing arm of SynthRestore). The AR57 was originally called the AR1, and briefly AR51, though the only difference was a 2 pole filter, as opposed to a 4 pole type, in the new model.

There are facilities for pitch cv, and gate inputs, plus an external cv control for the filter. There's also an audio input, for processing external signals through the synth.

  • There are still some pre-production prototypes Aurora AR51's available - pretty much the same synth, but with 2 pole filters (which gives a much more gritty sound). Please email for details.
  • Orders for synths generally take about 2 months for completion (we do sometimes have ready-built stock).
  • Each AR57 synthesizer, is assembled & hand-finished on-site, and is a truly British made product.

VCF trio board (multi ARP filter modules)

AVAILABLE NOW (built to order)

A NEW exciting product for 2014. Exclusive to SynthRestore.

This is a multi filter PCB incorporating 3 of the most classic ARP filters.

4012 (early 2600) 4023 (early Odyssey) 4075 (later Odyssey & 2600) .

The module core layouts are the same as the originals, and we have added the extra components required for operation (buffers etc). This means you can get as close as possible to the original sound of ARP synthesizers.

All you will require is some potentiometers and jack sockets, and you're away! Operates on +/- 15 volts, so can easily be incorporated into a modular setup.

We provide full connection details with each board.

VCO trio board (multi ARP vco modules)

AVAILABLE NOW (built to order)

A NEW exciting product for 2014. Exclusive to SynthRestore.

This is a multi VCO PCB incorporating 3 of the most classic ARP VCO's.

The 4027 VCO, was used in the ARP 2600 modular synthesizer.

The module core layouts are the same as the originals, and we have added the extra components required for square/pulse control. (along with sawtooth).

All you will require is some potentiometers and jack sockets, and you're away! Operates on +/- 15 volts, so can easily be incorporated into a modular setup.

We provide full connection details with each board.

This board is more cost-effective, than purchasing 3 seperate vco modules!

Minimoog replacement PCB's

Replacement PCB cards for the Minimoog model D synthesizer. These cards are made to the closest spec. using exact components (where possible) and matched transistors (where required).

The PCB track layout and component sizes are almost identical, therefore giving the correct signal path, retaining the same rich fat Moog sound.

Lovingly hand-built and tested in a Model D Minimoog.

ALL boards require 7 working days turnaround, as each one is built to order (unless we have some spares in stock).
