I googled up this link from a company in the uk:

Oakley Sound: High Quality Synth and Amp Repair

--------------------------------------------------------------------------------

What do I do?

I repair and modify all makes and types of electronic musical equipment. From a humble guitar effects pedal to a modern digital workstation.

I specialise in repairing analogue keyboards. I have seen many different types over the years but recent triumphs include: ARP 2600, Oberheim Four Voice, OBX & OBXa, TVS-1, Crumar Spirit, Moog Modular, Prodigy, Source, Rogue, Memorymoog and many Minimoog, Korg Mono/poly, Prophecy and Polysix, Roland JP-6, TB303, TR808, TR606, TR909, SH2000, VP330, System 101, Jupiter 8, Octave Cat (Original and both kinds of SRM) and several Prophet 5.

How much is it going to cost?

This, of course, depends entirely on the job. Initial inspection and job estimation will cost 20UKP which includes electrical safety tests. This charge is ignored if you decide to allow me to do the job. I charge 30UKP per hour, although the hourly rate does decrease if the job is a big one. The minimum charge for any job is 30UKP, and very few analogue synth jobs can be done these days for under 60UKP. All parts and any postage are additional to these costs. These prices do include VAT. You need to pay nothing untill the job is done. 1UKP is one pound sterling.
