the Case and Panel can be ordered with the PCB set
"The additional parts include:
ENCLOSURE PANEL
RACK EARS
DISPLAY LENS
Sliders
Noise IC
ALL MOUNTING HARDWARE:
SCREWS, NUTS, BRACKETS, STANDOFFS
(Motherboards have all DACS, CPU, audio CODEC, and headphone amp already mounted on them).
Note for builders:
- You need experience in soldering SMT Parts (around 350 SMT capacitors and 24 ICs in SOIC format).
- Tools are required: Soldering Station, Flux pen, magnifying Glasses, Oscilloscope, some pliers, tweezers, PC or Mac for installation of the boot loader and firmware
- Its preferred to have a bench power supply with current limiter for first test
- the programming is made by a ST-link programmer which is in the BOM (in case of DDRM builders - you can use the existing programmer)

Instructions for Calibrating
• First, put all CENTER DETENT pot/sliders in center,
• Go into MENU, CALIBRATION, SLIDER POT CALIBRATION, run
• (after 30 min warmup), Go to MENU, CALIBRATION, VCO CALIBRATION, run.
• MENU, CALIBRATION, RESONANCE. Follow this from the Jupiter 8 manual Turning Trim1 for each voice (or see below):
or turn Trim TR1 until the self oscillation is off on each voice.
