Memory extension

The extended memory modification was already installed when the Jupiter 4 arrived in the workshop. The original memory is extended from 8 to 128 memory locations which can be very handy, especially when doing live gigs! It was working when I tested it but to be sure Marc Marc also checked it thoroughly. It is working perfect!

External CV/GATE

Also the CV/GATE modification was already installed but it didn't work because off bad engineering. The modification was repaired and improved. The inside cables used for the modification were of very low quality and were all replaced. Also, instead of CV/GATE for two voices, it is extended to CV/GATE for all four voices. The voices can be triggered separately (4x1, 3x1, 2x1,1x1) or as an ensemble (1x4). Four new cables (Procab jack 6.3 stereo - 2 x jack 6.3 mono) will be included to connect the CV/GATE outputs to a sequencer or midi/cv converter.

Interior / Service

Cosmetically it is in good condition. Both side panels are damaged a bit on the front, and there are scratches on the front panel and other parts of the synth. There is also a tiny spot with corrosion near the VCF faders. But beside these imperfections the synth looks good. All faders and knobs are original. Some ugly keys were replaced by better looking ones. Also, inside and outside all dust has been removed, and all knobs and keys are cleaned one by one (see pictures).
