Hi, nice to be back...
I built two "universal" CCS "module" on the PCB. Marker and nail- polish, then Fe-III-Chlorid, as usual...Thanks Doug for the mosfets:-)
I added local decoupling cap 1uF/630V (not necessary). Dimensions of the board are 32x75mm. As you can see, I didn`t install R3 yet, I planned to use a fixed resistor. I tried both CCS with battery and they worked, but didn`t try it in the real circuit so far...
