Yo chorus72000, watch this:

BS2:

MODULE: current draw subtotal
------------------------------------------------
2*A-110 VCO = 140 mA | 140 mA
1*A-114 Ring Mod = 40 mA | 180 mA
1*A-115 Audio Divider = 20 mA | 200 mA
1*A-116 Wave Processor = 20 mA | 220 mA
1*A-118 Noize = 20 mA | 240 mA
1*A-120 Moog VCF = 30 mA | 270 mA
1*A-121 Multimode VCF = 30 mA | 300 mA
1*A-130 VCA lin = 20 mA | 320 mA
1*A-131 VCA log = 20 mA | 340 mA
1*A-138a Mixer lin = 10 mA | 350 mA
1*A-138b Mixer log = 10 mA | 360 mA
2*A-140 ADSR = 40 mA | 400 mA
1*A-145 LFO 1 = 30 mA | 430 mA
1*A-146 LFO 2 = 20 mA | 450 mA
1*A-148 S&H = 20 mA | 470 mA
1*A-160 Clk Divider = 40 mA | 510 mA
1*A-161 Clk Sequencer = 20 mA | 530 mA
1*A-170 Slew Limiter = 20 mA | 550 mA
1*A-180 Multiples = 0 mA | 550 mA
1*A-190 Midi-CV = 60 mA | 610 mA total current draw

-BS2 without A-130 (or A-131): 590 mA
-and then with an additional A-112: 640 mA
So it will work if you remove one VCA.

And by the way: If your modules consume more than 650mA, then not only
will your A-112 be "underpowered", but the whole system. Unstable VCOs
(A-110s) will be the cause (as happened in my sytem when the modules
consumed round 670mA)

cheers,
Paul
