DIY advice...

[James Coplin]

I like this last one.  Since it is selectable +/-12v or +/-15v if you choose
to change formats over from Euro to a +/-25v system you could use it.
Alternately, you could build a regulator board to knock down from +/-15v to
+/-12v, keep the supply running at +/-15v and power both 15v and 12v
modules.  3 amps is a bunch of capacity.  That is enough to run ~36 Modcan
format modules.
