Our Company repairs all makes and models of electronic organs beginning with organs of the valve era, through the transistor and integrated circuit technology, right up to the latest computer controlled instruments.

Ever since the introduction of the "Portable Keyboard", MOS has been active in repairs to these versatile instruments.

Requiring little, or no tuning, the electronic piano has enjoyed a prominent place in the home and professional environments. MOS has been at the forefront of service to these instruments, since their inception.

In the early 1950's, the guitar became "electric". Amplifiers were originally for the guitar. More recently they are used for the portable keyboard and piano and are used to improve the sound and power of these instruments. MOS restores all vintages of amplifiers - Valve, Transistorised and Hybrid.

In the late 1960's, the Moog Synthesizer made its debut. Since then there has been a plethora of companies producing these fascinating musical machines. Again, MOS has the ability to restore all vintages of synthesizer, up to and including the latest MIDI devices.
