Question Pass D1 I/V Stage Layout

I recall someone posting a PCB layout for the DI I/V stage can anyone point me to that post, I've searched but to no avail. I would normally just draw one myself using an etch resistant pen, however I've been quite ill of late (Hospital Job!) and I aint quite over it--- But! I'm itching to go again!

Default Your Keen!

Thanks for the effort but again I have the circuit diagram, what I am after is a Printed Circuit Track layout that a member posted (hand drawn on graph paper as I recall) shortly after the D1 Manual was made available. Actually (ironically) it was me that requested the Service manual or the circuit diagram of just the I/V stage from Nelson.

Here is a picture from Peter's D1 output stage from his 1704 based dac. There are pictures of his pcb in the thread. I just took a screenshot of his layout, which he sent me a while back.

Details and pictures of the pcb can be seen in this thread:
A nice dac to complement the Aleph-X.
