I assembled the K8064 dimmer and it seems to work. I use a 0-12v input and 230 V with a 650W theatre lamp.
However after a few minutes the low light settings start flickering.It seems to get worse the longer it stays on.
I have searched this forum and checked all suggestions (c12 = 100nF, TRIAC = TIC225M bourns, c13=0,47 uF). Only thing I haven’t tried is replacing the TRIAC. Are there any suggestions/solutions for where this flickering comes from?
