"The others relied heavily on integrated circuits from SSM or CEM. (Obviously they all contain discrete components--but the synth modules in a Prophet 5 or Oberheim OB-Xa are basically ICs with some support circuitry.)" I am currently recapping/restoring an Oberheim OB-Xa 8-voice. I just finished the power supply and now have eight voice cards that need about 13 parts, capacitors and mini-potentiometers, that need to be replaced on each. Each voice card has thirteen ICs but over one hundred discrete components. The main board has dozens of ICs and many other discrete components. The ICs replace the discrete components that comprised the oscillators, filters and VCAs but there are over a thousand discrete components in this synth. Comparing a Minimoog with a DX7 is apples and oranges. They were released 13 years apart. the Moog has one voice while the DX sixteen voices. The U.S. inflation calculator puts the Minimoog at $11,884 in today's dollars and the DX at $5,790.
