"Showing some of the classic analog sounds of an early-era Minimoog synthesizer"

"Beautiful, fully-working Moog Model D Minimoog. This thing sounds amazing. It contains the much sought-after "old oscillator" boards, considered by many to be beefier than those found in the later Minimoogs. The envelopes are snappy and punchy, the oscillators are thick and luscious, and the filter is 100% genuine Moog. No other compliments or descriptions needed on that last one.

The keyboard mechanism has been freshly serviced and feels brand new. Two common problems happen to classic 70's keyboards (whether Moog, Oberheim, Sequential, Arp, etc). First, the contacts get dirty with dust and years of grime, leading to squirrelly pitch fluctuations, inconsistent notes and generally a very unsatisfying playing experience. Second, small rubber pads inside many of the classics are beginning to dry up, deteriorate and fall apart. The keys develop a loud clapping sound and begin to feel clunky in a cheap way. In extreme cases, the rubber falls out of place and the vertical height of the keys are uneven. Luckily, the keyboard mechanism on this Minimoog has been serviced to avoid both problems. All contacts have been carefully cleaned, and the rubber bushings have all been replaced with new ones. This keyboard plays like it just rolled out of the Moog factory in New York.

The serial on this synth is 4766, and it was built in May, 1974 (see the picture of the assembler/inspector initials inside the case) when Moog was operating out of Williamsville, New York. Moog made three revisions to their oscillator boards over the years. The first version was highly unstable but considered to give the thickest sound. They quickly redesigned and created a much more stable board that wasn't nearly as affected by temperature/humidity. Toward the late 70s, Bob Moog made the final redesign, bringing even more stability to the board. Unfortunately, the general feeling is that this last revision has the least preferable oscillator sound. This synth received the second revision, which is the best compromise between stability while still retaining that monster Minimoog sound."

Monophonic After-touch Key Pressure Sensor Kit For Pratt-Read Keyboards

SCI Pro-One Aftertouch

YouTube Uploaded by FeedingTimer on Mar 10, 2012

via this auction
"You are looking at a monophonic After-Touch Key Pressure Sensor Kit designed for install into generic Pratt-Read keyboard actions used in vintage analog keyboard music synthesizers produced by manufactures such as ARP, OBERHEIM, MOOG and SEQUENTIAL CIRCUITS. This product is designed to replace the Modulation Wheel function. You won't need or want a modulation wheel once you've tried this product! Available in standard 37 key action. 49 and 61 key actions available for an additional $40 and $80 dollars respectively...

Center underneath the front of the keyboard as shown in the photos, peel and stick into place. Replace the 3 Modulation Wheel electrical connections with the 3 AfterTouch Sensor connections. Dry fit it first a couple times. You will likely need to carefully adjust the metal tabs to even out key actuation. Generally the metal tabs of the black keys may need to be lowered for even key-key actuation results. See key actuation photos. All Pratt-Read Keyboard applications may not be the same, there may be some mechanical adjustments required for your specific installation. Keyboard electrical connections may also vary from synthesizer to synthesizer so you may have to adjust for that as well. Please refer to the schematic and photos to determine suitability for your specific application!"
