Some technical tips:

1)  Use fewer 500 mfd capacitors.  There may be too much capacitance.  If not, 
use fewer larger value capacitors.  Probabaly the same price and size 
approx..  The value of capacitance depends on the transformer voltage, amount 
of allowable output ripple, and current drawn from the supply.  If the 
capacitance is too large, the regulator could dissapate too much power.  If 
it is too small the output ripple may be large, our the regulator can drop 
out of regulation.

2)  The transformer is potentially unevenly loaded.  There is a split 12v 
supply but not 5v.

3) The terminal labled +Ureg (unregulated) should be as variable, not 
unregulated.
