Hello!

 I'm new to the A100 and electroncs, my question(s) is about the PSUII
power supply. What is the wattage? The Doepfer website states that the
PSUII "has a max. current of 1200 mA for both +12V and -12V"...

Does this mean it is safely capable of driving:

A)  +12 @ 1200mA  and  -12 @ 1200mA

B)  +12 @ 600mA  and  -12 @ 600mA 
(the current divided across the rails)

C) some other combo of currents?

I keep reading about blown fuses and VCOs becoming unstable as you
start to max out the available current.

Do the modules use power evenly? or does usage of positive and
negative supply change, say, while an LFO swings from positive to
negative?

Thanks!

yes. That's the specification "the max. current is 1200 mA for both +12V
and -12V"

No. Normally the current@+12V is more that @-12V (but not for all modules).
If a module contains LEDs the current changes while the illumination of the
LEDs change. Even if a parameter changes (e.g. frequency) the current may
vary. But the specified current of a module is always the worst case (e.g.
all LEDs at max. brightness, and for @+12V or @-12V, according to which is
more). So you are always on the safe side if you add up the currents of all
modules of the system in question. The sum has to be less than 1200mA.
