@beic hi. Please see the thread above yours

There is no value mentioned there, and how did you calculated the tp peak of the sine for varistor against mains?
You just trow some varistor value in there without calculating anything for RMS and Vpp?!

I know it's an old topic, but I need to ask...

I read all this things mentioned on this topic, but at the end I did not find any answer to the fuses and for the varistor.

So, I wonder what values was used:

1. for fuses on mains 230v and for the 5V DC side?
2. I don't see any varistor values like 10D271K, 10D471K or 10D561K?

And also one suggestion about that thermal fuse, it would be better to use KSD-01 (normaly closed type) at 65C degree.

Dear @sundberg84 can you please read and write here the Varistors exact model/part number from your assembled board, please?
