OK amp builders....
Which is it! --- I'm feeling unsure of myself again.
The picture in my book for full wave bridge and a sine wave says:
Epk = 1.4 Erms.
Eav = 0.9 Erms
It also seems to depict the pk - pk value, the negative peaks "flipped" up to
become positive peaks, this to me would imply that you now only have more of
the same size positive peaks
BTW, it says the same for a full wave center tap, only that the piv seen on the
diodes is higher.
Now since I'm using a square wave, what happens? I finally found a reference
which said
Epk = Erms = Eav
Thanks for any extra clarification,
Paul, kg7hf.

Not correct!
With a full bridge rectifier you get the peak to peak voltage out as DC!
All the diodes do is redirect the transformer secondary to the correct
polarity.
What you wrote pertains to double rectification with a pair of diodes and a
center tapped transformer secondary.
