Here starts my own Building Documentation /Steps and Modification.

Schematic: TTSH-schematics.pdf
STATUS ADSR/AR finished on 09 March 2014
ATTENTION - wiring from PSU to the module headers are wrong "silkreen error" +/- must crossed - doublecheck before power up modules
Result from Widy:
BOM Failure - parts not listed
----------------------------------------
1x BC558b S&H missing ( need 9 .. BOM say 8)
1x 150K S&H fehlt ( not in building doc)
1x100p fehlt mir einer ( missing part )
1x 150K S&H fehlt ( not in building doc)
1x100p fehlt mir einer ( missing part )
parts left after build:
------------------------
1x15K
1x47K
1x1M2
2x100N Keramik
1x3p3 Keramik
1x47K
1x1M2
2x100N Keramik

1x1M Slider
first TTSH Kit arrived on 05.03.2014
Starts soldering the VCO Boards:
Online building documentation failure:
for VCO pcbs in zthees building website shows 1x61k9 but needed on each pcb 2x 61k9 resistors
http://thehumancomparator.net/4027-2/
Start assembly Main PCB
Use standoffs/Spacers:
Mounting VCO-1 pcb with long headers, but solder before 150K & 3m3
PSU with DC-DC Voltage "regulator"
right picture shows the X-crossed ferrite bead to fix the -15/+15V silkscreen error
VCO testing - wiring a +15v cable to resistor and probe ..
see my solution..
VCF picture - handle with care - 2n3904/06 - BC558 doublecheck the position near Tempco 2h
AR/ADSR
VCA
for testing: test with probe a VCO (need +15V cable see VCO testing above)
feed the VCO signal to the VCA and check the waveform with a oscilloscope.
