Mark, Michi124,
thanks for verification!
I already did the calculations with the same results. As it it these first time I use this experimental approach I was unsure of the value for Rs I got.
Regards,
Michael

Mark, this is my result for AMGIS L01-6364, 2x115V / 2x18v / 25VA, and i am confuse because Cs is 3 time Cx and no 15 time like your recommendation,
CX: 0,22uF
CS: 0,68uF
RS: 11 Ohm
fosc ~ 60kHz
I have a very hard time to check and use the Math for verification, by any chance do you have an Excel were we can enter the values we found ( Cx, Cs, Fosc) with the result of RS....for Zeta=1
Just got the PCB today See post Quasimodo 4

Oops ...
After all this time, finally remembered to post my results over here.
Using Hammond 229D40 transformers acquired from Mouser
"My" chosen snubber values are:
0.15uF, 0.01uF and 424ohms (I have a BUNCH of 196 ohm and 226 ohm resistors so easily made my "424"ohm resistor, but that much accuracy is not needed )

AnTek AS-3218 115v-18v
.01uF
.15uF
Primary shorted
1st secondary other shorted
10-12ohms
2nd secondary other shorted
10-12ohm
Both look pretty good, but I wrote 10R on the box for when I use it.
