## Building Steps
1. Split PCBs with a cutter and the edge of a table. Do not attemp to break it appart without putting it to an edge!
2. On components PCB: solder all 10k resistors (6 pieces) in. Careful not to confuse them with 18k!
3. solder all 18k resistors (2 pieces) in. Careful not to confuse them with 10k!

43. solder R32 with 1.8k
44. solder R33 with 3k
45. solder C2POTS with 220nF
46. Do not solder: push in the green pots (except PWM_CV)
47. Do not solder: push in the Jacks
48. Do not solder: push in the pot with plastic shaft
49. Put the Panel onto Pots and Jacks. Screw it on with the fingers
50. solder Pots and jacks (make sure everything sits tightly, before soldering the first things). Be careful not to apply too much solder at the jacks.
51. Take of the panel again
52. Split the two 5-pin headers (2x male and 2x female) into four 1 pieces. Use a cutter first and then split it with two pliers.
53. stack both boards with the pinheaders inbetween and solder the pinheaders together (if you are not sure they are straight, only solder one pin)
54. Put the ICs into the sockets (watch for the orientation! you may have to bend the IC legs to make them fit)
55. Put the Panel back on, screw everything into place
56. Assemble the Powercable
46. If your pots have a small metal piece, break it off with pliers (twisting usually works well).

57. Assemble the Powercable. Be careful about the orientation of the red stripe on the ribbon cable! Always measure the cable with a multimeter before using it!
58. Push on the knobs. If the knob is too loose, put a little piece of paper, isolating tape or plastic on the shaft, before pushing on the knob.
59. If you have a lab power supply (with the possibility to limit current), try your module with limited current first
