"This auction is for an original 1971 Mk1 EMS Synthi A synthesiser, serial number 4118, in its Spartanite case. The case has a few marks and scratches as befitting a 55 year old instrument, but no chips or breaks. The latches, although showing some corrosion, work perfectly.The Synthi front panel is one of the cleanest we’ve seen, being almost immaculate with virtually no panel marks and, unusually, no writing or marking absent or worn from the screen printing. In addition this example comes with the early chrome mirror finish knobs.
The internals are extremely clean and original with no modifications (see photo#4 now under the wrong thumbnail) and the unit has the genuine GE PA234 audio amplifier devices for the outputs and reverb.
The unit has been fully tested by one of the three or four people in the world who can call themselves EMS experts. It has been aligned and found to be working perfectly, and consequently given the original condition of the unit, no capacitors have been replaced. The original ones are working fine and show no signs of leakage or decay. However while the existing pots are electrically good with no scratchiness, some are a mechanically stiffer than current production models and the buyer might wish to have these replaced. This can be done at additional cost either here in the UK by EMS experts Lucid or by the buyer’s own engineer.
The Synthi comes with a full set of 20 patch pins and a new UK 240VAC mains lead (not shown). (Observant viewers may notice the absence of the usual Synthi A plastic name plate which usually adorns the outer case. This isn’t missing, but was simply never fitted as there are no holes for it, perhaps because of the early serial number. In addition the rear case is attached by four factory fitted screws and bushings, rather than the more usual arrangement of three)."
