- sort out all resistors in values: 1R - 999R, 1K - 9K, 10K-99K, 100K-999K, 1M-22M , same with capaciators.
- take a label/sticker on places where you have MODS/bugfixes like c20 cap, noise mod etc..
- take the TTSH pcb on 25-30mm spacer (use the BD236/BD237 holes too for spacers) you have to mount on each pcb side the spacer - so you turn the pcb for soldering..
- build the complete VCO- Subboards (so you dont have to look all the time for missing resistors points on the main pcb)
- solder all IC sockets on both pcb sides (LED IC on other pcb side)
- solder all voltage connectors (MTA´s) in the powersections and key cv, speaker etc.
- put all resistors in place on main pcb, beginn with the highest ammounts like over 60 x 100K ... if you have nearly 80% complete, its easier to place the rest section by section.
- solder all resistors from top
- turn pcb and cut all pins/legs shorter - so you solder all pins/legs in one step..
- if you have a VCO voltage regulator from nordcore, put a tape over the 100nF/10uF caps near power MTA header.
- Capaciators - begin with 100nF c0g for audio path, followed by 100nF for the rest,and all other caps.. keep Attention on filmresistors, i use film caps (wima) for VCF near matched trannys and the Filter sounds very good.
- solder all caps from front/rear.. keep attention on C20 cap
- put all diodes in place and trannys..(keep attention on c20, max noise fix, bridge instead of 2n5172 in clock, in VCF matched, sont mount the Amp. cooling blocks
- fill all LM301 in IC-sockets
- create the VCO header connection for all 3 VCOs..
- unmount the 25-30mm spacer and replace them with final 12mm and screws..
- solder all faders, at first with 1 solderpoint on every side, put the frontpanel on the pcb and check the fader orientation.
- final soldering for all faders..
- Jacks: solder on each corner 1-2 jacks, and 3 in middle, place the panel and then solder this few jacks.
- then place all jacks, bring the panel on top mount nuts on the jacks in corners and turn the panel, now you can point solder all jacks..
- switches.. unmount panel, put all switches in place and mount the panel, turn the panel/pcb .. the switches fall in place, solder a bit.. turn panel and check orientation on the frontpanel, if good , final solder ( please check the mechanical function of the switch before you mount them, sometimes you have faulty switches and its hard to desolder this..)
- build the power wiring cables and solder internal DC-DC adapter..
- initial check : disconnect all sections, check with DMM the voltage near DC-DC adapter.
- if you have a VCO regulator, build this and put this on the powerheader and drill a hole in pcb and mount a spacer,calibrate the regulator to 1214,6V
- test and calibrate the TTSH - good luck
