Agilent 6632B Binding posts

maat:
I have quite a few HP/Agilent 6632B in the lab and would like to convert them from rear panel outputs to front panel outputs. To do that I would like to replicate the option 020 A4 board. I found the schematics on p.77 in the service manual, but unfortunately the BOM on p.71 does not list the 4 inductors L601-L604. Does anybody out there have an original 6633B, 6634B, 6632B, or 66332A with 020? I would be very grateful if somebody would share the value of those inductors.
maat:
I finally got around to design a PCB to mount 5 binding posts to the front panel of my 6632Bs. I now have the outputs, sense connections and the chasis ground wired to the front.


In case someone is interested, I have but the design files on Github: https://github.com/PatrickBaus/HP6632B_binding_posts. I will update the github repo with the assembly instructions in the next couple of days.
bateau020:
This work, combined with Barbouri's work, inspired me to take what I found to be the best from both worlds and create an update.

The following changes were made to maat/Patrick Baus's original version:

- the terminals are moved around to match a more standard layout.
- added documentation about the connectivity to the main board.
- the wire connections are moved to better align with the hole in the chassis behind the posts.
- the slot in the PCB for the front panel fixation screw is widened a bit to allow more freedom.
- newer KiCad version (6.0).
- added a FreeCAD model.

Looks very nice. Good Work. My layout was inspired by some R&S PSUs, but you are right, the more traditional layout is different. How did you solder the binding posts? Did directly solder them to the PCB? I used wires so lessen the mechanical stress onto the solder joint.
bateau020:
Yes, soldered them in directly on the PCB. Easier, and with the fairly thick and dense 3D printed backplate on which I fastened the binding posts, the stress should be acceptable. But yes, wires would have been better.
Am working on a compatible option #760 relay board by the way. Will post about that when finished.
