Received here too thankyou. Beautifully arranged. And wow...aren't they small!
No R designations on the silkscreen....might need some hand holding!
Edit sorry had forgotten about the pdf!

Yup, I received my letter full of goodies also. Amazing job Ripster! I bet you have a very tidy kept household 😉
Thank you!
Is there a stuffing guide posted for the pcb’s?

He should have sent you BoM + schematics.
Placement cannot be simpler.
All Qs are labelled on the PCB.
The rest is obvious, and you can still refer to the pictures of the article.
(I'll post here again.)
The front side is same as before except "113" is replaced by "562".
The pads on the rear are Riv, Civ and the trim resistors for R1,2 and R5,6.
They let you trim both input and output DC offset.

Note that DC offset is affected by supply rail voltages.
So you should use your final regulators for offset trimming.
In this particular case, you do want a low-noise regulator with stable output.
I use LT3045/3094 myself.

I've read the article and threads and am still thick on one thing: single-ended I/V for AD1862 means 1 board and 6 devices per channel, correct? No need to double up for the AD1862's +/- 1mA output?
One board per channel for +/-1mA.
You have 5 boards because one is for test build.
And then you have 2 pairs marked R & L which is enough for 2 channel balanced.

Just had a pleasant surprise on my trip to the mailbox - received my package! Echoing others' comments on this thread, amazing job Ripster! Thank you! 😀
