Anthony - Page 21 looks like +12 is okay, but +5 recommended for the
tuning ones for stability.

This the same version of the manual you are looking
at? [1]http://www.doepfer.de/pdf/DIY_Synth_Manual.pdf

cheers, J.

Having jumped in at the deep end and purchased a DIY Synth I have been
busy trying to get my head around the connection of same. I spent 30+
years in the telephone industry most of it when the equipment was
electro-mechanical so never realy got into electronics. Now being
retired I have started to try and catch up with my education.
To cut to the chase I have mapped out all of my controls i.e. Pots
Sockets switches etc. but having studied the diagram on page 19 of the
users guide I cannot make out if I should be connecting +or-12v or
+or-5v to the following potentiometers:- VCO Tune, VCO Fine, VCO PW,
VCF Frequency and VCA init Gain. I read in the notes that the range of
VCO PW CV1 is shown as 0---+5v but it says the same for VCO PW CV2
which goes to PWM and this does not have a voltage connection. Am I
reading the diagram wrongly or am I right in thinking (I don't why) it
is +12v.
If some kind person could put me right and stop me blowing the board I
would be truly grateful.
