*Serviced* c.1987 Cheetah MS6 6-voice Polyphonic Synthesiser
The CHEETAH MS6 Synthesizer Module is probably the best analogue synthesizer available, delivering the most powerful synthesizer sounds at the lowest possible price. The MS6 is a Multi-Timbral Programmable Analogue Synthesizer Module, bringing classic synthesizer technology up to date at a fraction of even the second hand value of other synthesizers of this type.
Featuring Velocity and Aftertouch Sensitivity, WM Synthesis, and the Best Filter Circuitry, the MS6 has an enormous range of sounds, including: "House' Moog. & 'Acid' Basslines; Razor Sharp 'Sync' Leads; Powerful 'Fat' Brass; and Lusciously 'Warm' Strings.
Use the 64 Programmable Performance Memories to assign your sounds Multi-Timbrally into Layers, Splits or Monster Stacks which really can blast other synths into the background.
Over 400 superb sounds are provided, and these may be edited in any way you choose, using over 60 Program Parameters, Store your own custom sounds in 96 Programmable Memories,
You can link the MS6 to another MS6 to produce a Twelve Note Polyphonic Multi-Timbral Synthesizer for a fraction of any other comparable system.

The article describes Alex's experience with repairing and upgrading the power supply for this Cheetah MS6 synth module. Alex received the MS6 synth module from a customer after it had malfunctioned, causing a power outage in the customer's house. Upon inspection, it was evident that the synth had sustained fluid damage and had previously undergone repairs. As you will read, the original power supply of the MS6 is inadequate and prone to failure. To address these issues, Alex decided to design and build an external power supply housed in a steel enclosure, which would provide stable power to the MS6. The process involved reverse engineering the original power supply, designing the external enclosure, selecting suitable components, and extensive testing. Additionally, Alex implemented a "Live Forever" battery modification to replace the original Ni-MH battery with a lithium battery, preventing potential leaks and damage to the synth's circuitry. After completing the modifications and repairs, Alex tested the MS6 and confirmed that it was functioning properly, with all voices operational. Thanks to Alex's expertise in repairing and upgrading Cheetah MS6s, and addressing known issues with the synth's power supply, this example has been given a new lease of life and is ready to put to use.- Custom made 230V power supply manufactured by Plasma Music Limited (see Details from the Service for more information)
