Hello again! The mixer inverter ARP2600 clone modules are done--in and working!
 |
| ARP DIwhy modules with a friend's vintage 2600. Got USD $14K-20K to spend? you can get an original... |
More info about the project and design can be found in part II (here--original clone attempt...)
You also may want to skim part I (here): original thinking behind the ARP 2600 Voltage Processor project and cloning the "Increase lag time" sub-circuit.
 |
| Cloning these 3 sliders and their surrounding circuitry! Euro format.... |
I have posted gerbers, BOM etc. for two clone modules. One is the equivalent of sliders 1 and 3 above, with a pot controlling normallized control voltages, the other has pots to attenuate 2 input signals; on both, summed outputs are inverted, same as the original.
To build both you will need 2 boards and 2x front panels:

In general this is a super easy single op amp build, it took me less than 2 hours to make both versions of the ARP 2600 mixer-inverter voltage processors.

| 2x inverters with the lag processor you can read about here. |

| More A-B testing with voltage processors in a vintage 2600.... |
Easy!!!
More ARP clones on the drawing board...the Electronic Switch for instance? Until then, have fun and don't breathe the fumes.
