Question Datasheet psu, 0.1v to 50v @1a...

HERE :
(page 12, Figure 14)

...My question is, what would come between this regulator circuit, and the power transformer.......bridge and smoothing caps??

...And what transformer say you?

You'll need 35-40 VAC, 70-100 VA, 2200-4700 uF in smoothing.

I friend of mine built this PS long time ago and it worked pretty well.

...or is that a drasticly different circuit altogether ?

You can built two identical PS and then connect them in series. This will give you a dual suuply.

OK, so using a center tapped tranny....
positive is one psu,
negative is another,
....and 0v (ground) is shared with both.

Correct?? ( )
