So I'm laying out a PC board with some snubbers on it, the type Jim Hagerman discussed in his article in audioXpress a few years ago, RC in series hanging across the transformer secondary. Two of them, in fact, for a center-tapped transformer. And a layout question occurs to me.
There's a terminal where the center tap of the transformer attaches, which is about 0.35 inches from the ground terminal of the first filter capacitor. (Not a balanced supply; this is for tubes.) Nice thick trace, since the major part of the ripple current flows through it.
So...do I run the trace from the two snubbers to the CT terminal, or the capacitor ground terminal? My first guess is the CT, since that way I'm hanging the snubbers pretty directly off the transformer secondary (and it would be handy for layout reasons). But it'd be nice to have some more expert advice.
Peace,
Paul
