update: 03.February
original TTSH rev.2 build guide should be updated in next days h= ere: http://build.thehumancomparator.net/
Muffwiggler build thread: https://www.muffwiggler.com/forum/viewtopic.php?t=3D130493

check the rev.1 build guide for more documents

Release notes:
The second PCB release aka v2 release was released February 2015, = the naming of v2 is related to the second sale from zthee, its not the same= as zthess internal releasenumbers.(v7.2)
This Description is for Builder with experience in parthandling and sold= erjobs - otherwise check: http://build.thehumanc= omparator.net/
Changes between first Version and rev.2:
- Powersection, two 1 inch voltage DC-DC converters, embedded powerregul= ators like nordcores pcb addon on rev1 , 3x SMD inductors/chokes and more= p>
- Amplifier : new design without cooling, other Amplifier Transistors an= d some other parts in this section
- LED Driver redesign
- multiples on pcb
- speaker holes
- switches: you get with the pcb kit few small pcbs with - this are used= like a washer for the switches, in result switch mounting is easier as in = TTSH rev.1 (pics on my website)
- some minor fixes
This Guide is only for DIY Guys with experience, i=C2= =B4m not responsible for defects or usage issues.
short: dont use the onboard powersupply due to EMV i= ssues - the DC_DC section bleeds in the VCF in result of high frequency ton= es
check the T=
TSH 230V/110V Powersupply page
for internal 110V/230V powersupplys only (like powerone hbb1.5/h=
aa0.8) see here
only for REV."2" (v7.1 on pcb top right corner)= p>

please add: 6x 100nF SMT c0g caps in size 805 <=
br>
mouser part 100nF 77-VJ0805Y104JXXPBC
10nF works fine too (its only a decoupling cap)
3x Timing cap 680pF needs a polypropylene, polystyrene or=
silva mica cap(7.5mm footprint)
mouser: 80-PHE450HK3680JR05
you can try the usage =
instead of SMT inductors/chokes this:
http://www.re=
ichelt.de/index.html?ACTION=3D3;ARTICLE=3D86466;SEARCH=3DL-HBCC %20100 =
(add enough soldercore to the pcb pads, bent the leads and solder this to =
the pads)
notice: the usage of 1k87 tempco=
3300ppm instead of 3500ppm works fine too.
DIFF from Version 1to version2 (first TTSH from early2014 t= o second from early 2015)
http= ://thehumancomparator.net/wordpress/wp-content/uploads/2014/05/v1-v2-difffe= rences.pdf
Minor Bug/improvement: use a BC337-16 instead 2N5172 in= the noise section more Details here (you don't need further mod= s)
= span>
Major Bug= strong>
Description= : the onboard DC-DC adapter (Murata) bleeds in the VCF (EMV - high= frequency)
Solution: <= /strong>use a external 110/230V powersupply or a other powersupply with 15V= /-15V outputs and connect it on the 3pole MTA156 header (dont assemble the = onboard power section)
check the <=
a href=3D"/pages/viewpage.action?pageId=3D17235998">110V/230V powersupply p=
age
works for most parts too..
update: 01.October2014 - jumpers, speaker workaround for testing
The first TTSH was build with zthees Builders Guide and works fine, but = its not effective to solder section by section.
from my second TTSH on I built them after these steps:
This page is only for me :wink:
i dont support Main Power handling (ich supporte keine 110V/230V Bastele= ien)
in case of usage of 110V/230V powersupplys dont add the parts for the on= board regulator (TTSH rev.1+2)
use the frontpanel power switch for the LED driver TL071 socket to switc= h the LEDs on/off.
make sure you have a Main current fuse for the powersupply, typically i = use IEC power inputs with linefilter and double fuse.
use rubber feeds otherwise the case "swings with the transformer frequen= cy", you can hear it in the big ttsh case like a speaker.
tip: by usage of a internal 110V/230V psu - mount the psu in left = corner and reverb tank on right/top corner with in/outputs to top - or you = get a massive hum in reverb.
mount the psu on plastic/rubbers - because the empty case amplified the = psu noise/hum/vibration.
Info for users with embedded switched = Murata/TDK.. regulators:
(if you have added the both switched regulators, desolder the 220nF caps= , 100uH caps)
For new build: (rev.2 aka 7.x pcb version)
for condor/powerone hbb1.5 powersupplys:
cut VW1 and VW2 on pcb, run wires at the output included sense
picture shows 230V usage (Mains Input on transformer is different = for 110V AC)
measure the 15/0/-15V before you connect it to the TTSH. if needed use t= he psu pcb trimmer to change it to the correct value,
recalibrate your VCO V/oct and VCF 1V/oct if needed.
for condor/powerone haa0.8
only the transformer input 1+4 or 1+5 (for 230V) bridge the 2+3 pin, no = trimming needed, measure the output
the usage of rubber feets minimize some vibrations from the transformer.=
mount the reverb tank at top with in/output orientation at top or you ge= t some hum from the PSU.
mount the PSU only on the left case side - on the right side is the reve= rb input and its very sensitive of magnetic fields.
