Up for sale is a Sputnik Modular Dual Defect Processor Model 289 Buchla format DSP module built by me, featuring blue Rogan knobs.  The module has been properly tested.  It was used for a period of time in my smoke free home studio, but it is in perfect working order and mint cosmetic condition. This build features the signal attenuation modification suggested by synth restoration specialist and Buchla module builder Dave Brown of ModularSynthesis.com, who noted the input levels were a bit too hot for Buchla standards (I can attest to this).  The modification involves the increase in value of 4 x 100K resistors on the back (i.e. exposed and easily accessible) PCB.  These were replaced with 220K resistors.  I made custom sockets for these components so that they may easily be swapped out.  I am including a set of 4 x 100K value resistors cut to size in case one should feel the input signals are too weak and they'd like to replace them, but I don't think that will be the case.  4 x 4-40 screws are included, as well as a cheat sheet for operation.  This is the DIY version which comes loaded with the following algorithms:

Upper Patches
1. 2-Tap Proportional Delay
2. Harmonizer
3. Filtor
4. Phasering
5. Yuverb
6. Rail Resonator

Lower Patches
1. 4-Tap Rhythmic Delay
2. Psychorus
3. 8-Band Correlated Comb Filter

8. Brainulator
