This page is only for me 
i dont support Main Power handling (ich supporte keine 110V/230V Basteleien)
in case of usage a 230V powersupply dont add the parts for the onboard regulator
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 frequency", you can hear it in the big ttsh case like a speaker.
(if you have added the both switched regulators, desolder the 220nF caps, 100uH caps)
cut VW1 and VW2 on pcb,
picture shows 230V usage (Mains Input on transformer is different for 110V AC)
