Moog (in the USA) updated some control components in the 901A Oscillator Controllers (not the Oscillators themselves) so that the 901A Oscillators can now tune to scale across the full 5 Octaves. This modification does not of course alter the Oscillator tone.

Many of the yellow labels on the modules are no longer attached. The seller in 2014 did not know why these labels had been removed but it’s something that had been done during the lifetime of the instrument. Some modules have their yellow tags still attached, so you can see these from the photos of the reader of the cabinets below, but these are all 100% genuine RA Moog modules.

The RA Moog has been stored in our secure facility for 10 years, so will require servicing, but we are not having this work carried out in advance of the instrument going up for sale, the reasons for this are as follows: Depending on your preference, will can have Vintage Moog specialist synth-tech, Kent Spong at KSR, carry out the servicing work once the sale is completed but we will not include restoration work to any of the modules or the wood cabinets as this historic instrument needs to be protected and conserved in its original condition. This means any servicing would be carried out sympathetically and would clean and refurbish any parts as necessary but not replace anything unless it’s a critical requirement to ensure operational stability. Some buyers may have a preferred tech do this work or in fact might prefer the Moog to be left untouched. If you would like us to have the RA Moog serviced by Kent at KSR (5000GBP paid after the auction, not via VEMIA), then the system will come with a 3-month warranty from us. If you prefer to take the RA Moog ‘as-is’ and make arrangements to have any servicing carried out by your tech then we will not be providing any warranty on the sale of the instrument. This RA Moog Modular came from the factory as a US 110V system, so we had not modified it in any way from the factory stock spec. All three cabinets operate on US 110V. We will supply two step-down transformers for use in the UK/EU in the sale. We do not have any original user or service manuals or cables with this system, other than the power cables for the cabinets.
