This guide isn´t complete yet, i still work on it. ( last update on 22.Dec.2016)
open tasks:
- LED-man add a trusted builder list
- give trusted builders write permissions here
BOM: (Bill of material)
the shared mouser basket from thehumancomparator is wrong (22.Dec.2016)
(this Mouser basket was provided in the ordering eMail)
https://www.mouser.de/ProjectManager/ProjectDetail.aspx?AccessID=234c0 9ed60
delete from this mouser basket both parts:
652-SRN6028-101M
710-744290321
this chokes/filters aren´t needed in rev.3
printabel BOM as list, (rev.2 plus additional list for filter and psu)
ttshv2BOM.pdf (mainboard pcb)
4027v2BOM.pdf (vco boards)
TTSHrev3_SecondFilter_BOM.pdf (filter board)
known issues:
- Powersupply Board - turn the 2pol MTA156 header if needed - otherwise the power input cable is above the powersupply.
confirmed - Main board – Missing trace from V- to header. (copyright of picture for thehumancomparator.net )
- 4072 VCF missing trace pin 4 on LM1458 to -14V
- 4012 VCF Board — BC558 should be installed backwards
buildguide:
This guide is for users with experience in SDIY, you need a scope and a frequency counter, DMM/DVM/LCR-Meter)
i dont share infos about polarity of capacitors, this basics skills are required, otherwise feel free to ask me for a assembly service. (check the trusted builder list)
please use a fume extractor.
its needed to solder 6 SMT caps in 0805 format and 2 SMT power regulators.
this guide is a best practice guide, i´m not responsible for failures/malfunctions/defects.
- lets start with the powersupply board - add all needed parts on the pcb, start with the two SMT power regulators.
there is one missing part (a dual choke) - please use wire links here or resistor legs
turn the 2 pol MTA header as described in the picture
if needed - wash the pcb carfully on the solderside
