I'm wondering if it's worth the effort to snub a TO-220 bridge?
I put a snub over my secondary winding (a 220uF and 330ohm resistor in parallel across the secondary) and given TO-220 are pretty clean I am wondering if I should bother.
I need to do it all by ear, no breadboards here, so a lot of effort to A-B.
Thanks

You don't need to "snub" Schottky diodes as they do not have a p-n junction to deal with.
However, they do turn on/off which the RRSF can minimize the effects of.
I leave the filter across the secondary winding. This can be seen on the oscope.
220uf is rather large - consider 0.01uf - 0.033uf HV snubber caps.
Verify your voltage with the link.

Ok cool.
Yeah, meant to type .022uF. I think my caffeine levels were depleted when I typed "220" instead of ".022". :-(
thanks

Sure thing.
PM me if you want the RRSF schemo for both the FWR. and FWBR.
Cheers,
W
