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.

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?? ( )=RR= |
