Hi everyone,
I've been looking for a circuit for a 15 V, 5 A
four-quadrant power supply powered from 110 V AC.
So far I've found :
http://www.reed-electronics.com/ednmag/article/CA371090
the schematic :

which looks OK to me except for the current rating (fixable)
and that weird LT1970 for which I can't find the Spice model.
Any thought regarding this circuit ?
Any other ideas ?
Since for me the educational effect is more important than
e.g commercial viability or efficiency I'd prefer a design based on
off-the-shelf (more likely out-of-the-parts-bin-except-for-
the-power-transistors) op-amps and tansistors.
Any pointers appreciated.
(And no, this is *not* a homework assignment)
