Hi,

I have largely finished the design but it's designed to support the HP-419A
and Fluke 845A, with an isolation circuit for the HP-419A.  Unfortunatley,
I have not had time to finish the implementation (PCB design and build) due
to a heavy work scdhedule over the last year, and its not getting any
better in the near term.  I am more than willing to share the design with
you or anyone else that wants it.  I can send a set of hand-drawn
schematics of the circuits to anyone who wnats - just send me an e-mail (I
don't have a web site to host the data - I should get one).  I have a lot
of suppprting documentation such as LTSpice simulations, technical
articles, etc. also.  I can anwer any questions anyone else has on the
design if needed.

Hi Randy,

I would be happy to go on with the modification (for the HP 419A).
Will also rout a PCB - plan to use EAGLE (V6) or maybe Altium Designer 14 (not yet used to).

Any information (ideas, sketches, notes, files...) is highly welcome.

I don't have an account for upload either, thus simply send to my private mail address: Ludger.Lenzen@gmx.de

For sure it will no fast-finished project, as my wrokload is high also. But promise to keep you tuned on the progress via your private mail: randyevans2688@gmail.com

Hi Randy,
 
I have just installed a 2GB "dropbox" (thanks for the tip, John).

That's the link:
