Some other strange thing I noticed this weekend with the oscilloscope at hand..
I own one a132 and two a130s. The two 130s are of different generations, which I don't
object to so much.
What I did is the following:

I patch the output of an a118 random voltage into an a172 max/min.
As second input I input a constant voltage from my a176 to make sure that the max
output of the a172 puts out only positive values.
This goes into the vca as signal and then I take an envelope as cv input.
This in all the cases delivers a positive voltage output you would say...
However my a130 of the second generation presented a negative output, to my surprise.
All the other mentioned vca's behaved as expected...

Is something wrong with my a130(second generation) or is this an intentional design
thing.. (would be strange if you'd ask me)
