" Power Supply Rebuilt – Re-capped entire power supply with rare and awesome-sounding Samwha RD caps. Samwha caps, in general, are difficult to obtain here in the USA. However, many top notch OEM’s know how good they sound, which is why Marshall, Moog & Orange amps use them almost exclusively in their production. This alone, should speak volumes about their “tone”. However, as an OEM audio engineer, I have access to these wonderful caps and they are “sonic-sleepers” in my opinion. They sound awesome in quality analog synths too, of coarse, yielding big, fat, fluffy, smooth tone. Far superior to Illinois, Sprague and other brands. Try them for yourself, (if you can get them) and hear the difference!
Power Supply Rear-mount TO-3 regulators – were all replaced with custom gold electro-plated units. (Not available on open market, as these are custom plated parts).
Power Supply cable harness- rebuilt with thicker, high-quality copper strand wiring. This helps the power supply “breath” better due to reduced resistance.
Power Supply 723 regulator sockets- replaced; gold plated.
Power Supply 7815 (+15VDC)regulator – replaced; gold plated.
OB-8 Main processor board – Every IC, carefully removed, cleaned, tested and/or replaced as needed.
Power Supply trim pots - replaced with Bourns “plastic-conductive” type, The very best sounding trims available, since all pertinent power supplied to the OB-8’s specified pcb’s must pass through these pots. (Plastic conductive material has a superior “open” tone compared to carbon type pots).
OB-8 Voice Boards - were removed and cleaned. All CEM VCO & related chips were removed and cleaned and replaced with socket enhancement fluid. Both OB-8 voice boards also had all major capacitors replaced with Samwah RD caps.
OB-8 Panel Pot Boards - were removed and cleaned and all pots thoroughly cleaned, lubed and tested.
Special audiophile-grade solder -used on all replaced components for maximum sonic tone and transparency.
Midi Output Jacks -all replaced with Nuetrik/Rean brand.
Bend Lever Assembly -fully cleaned and lubed, All IC’s removed, cleaned, tested and/or replaced.
Keyboard assembly -was removed from chassis and disassembled. Rubber boot contact covers were removed and cleaned. Keypad contacts were all replaced with Sound Doctorin NASA type conductors. OB-8’s are notorious for key contact and misfire issues over time and this solution is the best yet.
Side-End Caps - were refinished/painted with special “stainless-steel” particle paint and then clear lacquered with many coats to achieve glass-like finish. Absolutely stunning and totally says; “I’m Special”!
Inner Chassis - was completely cleaned and new black colored end-cap fasteners were employed.
Fresh Data Dump - was re-loaded with Standard patches.
Midi & Arpeggiator Included! – This OB-8 has both midi and a fully functioning arpeggiator, which is not found on other Oberheim models such as Matrix 12, OBX-a etc.
Owners Manual & Technical/Schematics Manual - both included and bound & printed on high-quality gloss paper!
To top it off, the unit went through a full final check-up with Five Star Engineering in Mesa, AZ. (Dean there,is an ex-Oberheim employee/tech and extremely knowledgeable)! Unit is in full working condition."
