My bench power supply (the Atari Orange box) has been modified to provide:<br>
+5VDC @ 15 amps<br>
-5vdc @ 1 amp<br>
+12VDC @ 1 amp<br>
0-24VDC @ 2 amps (floating so it can be positive or negative supply)<br>
and the two Variacs that create up to 80VAC at 2 amps. (2 X 40VAC center tapped each is floating)<br>
<br>
I find this covers almost all the boards I ever need to test.<br>
<br>
A computer switching supply would handle most of these other than the variables, and a Variac and transformer would handle the rest for your bench.<br>

I have seen vary wildly in their specs.<br>

Suggestions?<br>
