Hi everyone! I have a question about snubber capacitors. Do I put those before or after the rectifier bridge?

Another question is about varistor. I have transformer that outputs 25v-0-25v. I was thinking to put varistor rated at 60v across two coils. Will that work?

Attaching schematic.

Thank you all!

The snubbers are always between the power transformer & the bridge diodes. Using Quasimodo gives you the exact values😉
