Sequential Circuits Prophet 5 Rev. 2

via eBay

Serial #2288

Update: it's a Rev 3. Compare the right knob placement to this Rev 2. Caught by Heath in the comments.

Update via Onkloud in the comments: "my auction and my mistake it will be relisted with proper info"

Keep an eye out on Onkloud's other auction listings in case I miss it. Tons of other items there as well.
