Doepfer

Sorry for this interesting, but slightly off-topic posting:

for those of you interested in the mods I did on my Analogue 
Systems ADSR, go to:

http://www.allegrobikes.com/franken.html

and click on the the link 'modifications' in the first paragraph of 
descriptive text on the expansion panel.

I have one queation to you, Peter, since you have a bunch of 
different euro-modules in your systems..
My current setup (a reeeaaal small one compared to yuors) cosists of:
An AS Filter, Osc, Doepfer amp, controls, etc.. isn't important to my 
question actually.
I have a Analogue Solutions Power supply board, on which I can plug 2 
ASys modules into (the Osc and the filter). I do want to expand my 
system with a frequency-to-voltage Asys thingie and add an extra 
filter and Osc, maybe an extra Osc ass a waveshaper LFO. Or could I 
get the same results with a slew limiter(?). So, what I was 
wondering, how did you supply the volts to your AS modules?
Did you built connectors/or cables yourself (hopefully)?

soory for the late reply - I have had some family issues regarding 
the health of two of my good friends, my dad and my dog.

I have currently 3 different power supplies for my system:

two Doepfer's, which run all of the +/- 12 volt stuff (analogue 
sol/sys, Doe and my homebrew stuff)  and one linear Condor 
+/-15 volt supply for the Blacet, Buchla, MOTM and Oakley stuff - it 
will also power the Wiard Borg when I get that.

The 15 volt has a current load mlimit of about 1.5 amps and the 
two doepfer's together get me to about 1.2 amps - plenty of 
power for synthesizer modules.

Yes, all of them MUST be linear (constant current) instead of 
switchers (interrupted current).

I already have other +/- 15 volt and +/-12 volt supplies, which are 
smaller (less current capabilities) that I will in time put in the 
expansion module so that that can run by itself and be taken 
around (the main unit wieghs WAY too much to be called 
portable).  

Right now, all of the supplies are layi8ng on shelf that the 
system sits on (there's an extra 9 inches back there.  I am 
planning on putting them all in one neat aluminum chassis box 
shortly (I've got the box, but I've become lazy!  at that point, Im 
probably going to have a row of screw terminals to connect the 
various power cables from the rows of modules.

It all works great - I suggest you tie the grounds together of the 
various units at the supplies and do not rely on the patch cords 
to make that common connection.

Hope this helps,

Peter

Hello Peter and David,

Thank you for all the information about power supplies. It might come 
in handy when I'm going to build an external controller cabinet for 
my 2 theremins and maybe a sequencer and other CV sources..

There's still one thing:
The links David posted about the veroboard doesn't really work. I've 
checked out maplin, searched there on "veroboard", couldn't find 
anything with that. I did find a lot of other stuff (stripboards?). 
But I don't  know if that would be the same thing..
