"Lewis"
I've seen the basic schematic of a four-pin full-wave tube rectifier
depicted at least two ways, and I'm confused. I've seen it this way:

In this configuration, what is done with the center tap of the 5V winding?
** Huh ?? There ain't one.
I've also seen it where the B+ appears to be taken from the center tap of
the 5V windings, like http://www.anthemav.com/OldSitev1/pdf/taste.pdf
(page 28)
Assuming both of these are acceptable, which is preferable and why?
** If there is a heater CT - then use it for the DC out.
Supply ripple voltage will be more symmetrical on each half cycle -
eliminating any 50 /60 Hz component.
