RE: Broskie

You and Broskie seem to use the same or very similar symbology programs to create your schematics.

I think if the filter is only a single C, then the junction of the two caps would have to be connected to ground, as you show. I think (emphasis on "think") Broskie's point was made using a CLC topology, as I mentioned above. In that case he suggested to ground only the C2 capacitors. The C1s that span the pos and neg nodes of the FWBR should not be grounded for a true balanced supply. I hate to be in the position of quoting Broskie, but I cannot find the reference on TCJ, either. I will look more later tonight. Anyway, when I tried it both ways (grounding C1s vs not grounding C1s) in the bipolar supply for the front end of my OTLs, there were differences in the pos and neg voltages relative to one another, and the 'scope picture was different.
