Doepfer

Hallo!

Well, I know I've asked this question before, but I never got a response.  No worries, I know I'm a little off topic.

I'm building a module for my Doefper A-100.  Does anyone know which jacks (manufacturer/part number) are used by Doepfer, Analog Solutions, or Analog Systems?   Are there any other jacks that could do the job?  I'd like to solder the jacks directly onto the PCB board like they do.  The jacks should be threaded like Doepfer's too.  

Thanks!
- Bret

On the Doepfer site go to: Prices, scroll down to: Klinkenbuchse 
3.5mm / 3.5 mm jack socket print version (almost at the bottom - 
thats the "Doefper jacks" and for only 1 Euro.

Hi Bret,
The jacks Doepfer use are made by Cliff, and are available from a 
number of sources in the UK:

Maplin, order code CX94C, 49p (inc VAT)
www.maplin.co.uk

Rapid Electronics, order code 20-0140, 30p + VAT
www.rapidelectroncs.co.uk

Somewhat annoyingly the pins are 0.4 inches apart one way, and 0.15 
apart the other: if you're drilling your own holes no problem, but 
for 0.1" pitch strip board you'll have to bend two of the pins (I 
twist the 'back' pair by 90 degrees, then you can angle them to fit 
in the hole 0.2" from the front pair).

Hope that helps!

Tim

Does anyone know if Doepfer uses switching jacks on any of its modules, or
are they all just tip and ground?

The Cliff jacks *are* switching jacks, but on most modules they are 
not connected as such. Doepfer often say a signal is 'normalled' to 
some other signal when it is used in a switching capacity. A quick 
scan of the modules I have revealed these: 

A108 'feedb' - from 48dB output if no plug inserted
A110 'CV1' - from bus
     'sync' - grounded
A127 'ext CV' (x3) - from internal LFO
A134 'audio in 2' - from 'audio in 1'
A136 'ext level' (+ and -) - from +L, -L pot resp.
A140 'gate' - from bus
A156 'trig in' (x2) - from internal clock
A179 'ext LDR' - from internal LDR
A199 'ext feedbk in' - from 'reverb out'

... and there are probably more in other modules I don't have!

Hi James,
Sorry for correcting you, but I thought I'd clarify a few of your 
comments, so that confusion doesn't arise...

The jacks only have 4 pins (and not six).
None of the modules (some 40 or so different types) I have are 
doubled sided PCBs - they all only have copper tracks on one side. 
However, you are right in that it would often be tricky to do what 
you want to because often the jacks *are* mounted on the solder side, 
and so would required their removal to cut the track underneath.

I think the CV1 in on the A-110 VCO is a switching jack.

All the jacks I've looked at on Doepfer modules are Switching types, though
the switching function is seldom used. They use this type of jack because it
has more legs to go through the PCB (stability and strength), six instead of
three. Most of the modules have traces bridging across both the switch and
contact legs. I was going to use the switching leg to make a "normalized"
synth starting patch, the common VCO-VCF_VCA sort of thing, but because the
traces are sometimes on both sides of a double sided PCB, you would have to
remove the jack to cut the top trace. It would be nice if Doepfer did what
the old Emu modular did, offer all the switched contacts on the PCB with
headers that you could wire to. If the Switched contacts on the Doepfer
jacks just went to unused pads (cheaper than headers) that would be very
useful for making normalized patches, mot to mention making a Vostok type
synth with a ARP 2500 switch bank or EMS patch matrix that always could be
overridden with a patch cord.

hi bret,
i'll forward your message to doepfer....he will maybe
answer your question....
bakis.

Your very right, I was going from memory (not willing to pop open my Doepfer
portable racks to look), 6 pin would be stereo TRS type. And for the
soldering, the memory was failing again, I was thinking of the instance
where the jacks are soldered to the trace side of the PCB. This is a bad
practice to my mind, but unavoidable with the space considerations. It is
not nearly as stable as through PCB to pad. It is much easier to rip a part
off the trace side of a un-plated through PCB pad than trying to pull the
soldered  pad through the hole.

Hi!!  Thanks everyone!  Your comments have been amazingly helpful.  
I've ordered some jacks from Cliff Components.  Hopefully I can kick 
this project into high gear. :-)

I'm going to use ExpressPCB to do the PCB board, and I may use 
http://www.frontpanelexpress.com/ to make the front panel.  Very fun!!

All jacks are basically switching types (four solder pins for two
contacts), but very often the pcb layout makes a switching use impossible.
I changed a lot of modules to a switching mode, but the swicthing mechanism
of the 3.5mmm jacks is not very reliable. Meanwhil I tend to add a real
switch for these functions.
