As promised, I have uploaded some oscilloscope screen shots from my
breadboarded. They are located in the Wave Rectifier folder of the
files section. The input signal in the shots is a 1.5kHz 10Vp-p sine
wave. The offset control in the gven examples was set such that
rectification occurs around approx +2.5V rather than 0V.

There is also a quick mock-up front panel showing what controls and
connections I propose to put on the module if and when I decide to
manufacture it. This was a cut and paste job from module images on the
doepfer website and is meant as an indicator only since it would be
very wrong for me to produce a module that looks exactly like a
doepfer one.

Dieter, I would be interested in the schematics of the A-136 merely to
check out the modifications you suggested.

Jari,I will put through my A-136 through it's paces if I get time
later this week (unless somebody else beats me to it).

Cheers,
Adam-V.
