Snubbers on Power Transformer Secondaries

I didn't say I "wanted" agreement, I said there doesn't appear to be any in this case. Of course it would be nice if there was one sure answer, but like many other topics in life that doesn't seem to be the case here.

My interpretation of the consensus in this case is that one snubber across the entire secondary is adequate, and one across each half to CT may be a little better; perhaps a case of diminishing returns. Being somewhat obsessive, and given the low cost of the parts involved, I think I'll try the latter.

Thanks to all!

In a regenerative receiver I made, I put a snubber across entirely secondary winding of 1K and .15uF on a 170 + 170V to the plates of a 6X4. Placing across all secondary you are snubbering all leakage inductance. As DF96 tells, there are magnetically coupled, but not only inductive, also capacitivelly, and the linkage is not 100%, so there exists a leakgae between secondaries itself.
