"This is a 73-75 Serge system with 2 panels, the Voice and the Control. Both were put together from the eDIY sets that were offered at the end of the year in 2019. In addition, LEDs were added to 2 of the slews, the envelope, and the SSG modules. This makes a big difference when using, as it provides feedback. The 2 open holes in the control panel were fitted with toggle switches on the negative slews, so you can make them cycle. Both panels have been calibrated.Both hammond boats are connected together by 4 screws inside, as well as a rubber grommet that provides a channel between the 2 for the power to be distributed. The panels were fitted with potentiometers and then wired to the boards, which took a lot longer, but this gives you flexibility if you want to do future modifications. In fact, I'd recommend someone diy friendly buy this if they'd want to add more toggle switches, LEDs, etc. The PSU is a frequency central power unit that has a +6 volt regulator, needed for this Serge design. Jameco AC adapter included to power both panels.
Cosmetically, this is listed as 'very good' since there is a little bit of rash under the mounting screws and a few small marks here and there.
Comes with a bunch of banana cables from modular addict of varying color and length."
