Folks,
I have 10 AD1862 dac boards and PSU2 boards to give away (ie 10 packs of 1 1862 board and 1 psu2 board). I got extra made when me and some fellow diyers here were making the DACs. I had anticipated needing more spares but the builds went so smoothly none of the spares were needed.
The DAC boards are V1.3 with through hole opamps as shown in this post:

The PSU2 boards are v1.0 - LT1963/LT3015 version as shown here:
https://www.diyaudio.com/community/...2s-input-nos-r-2r.354078/page-74#post-6530277BUT bear in mind there is a change in resistor values to hit the target voltage:
https://www.diyaudio.com/community/...2s-input-nos-r-2r.354078/page-78#post-6551192AND a recommendation on 2r2 resistors on the rails:

I've been extraordinarily blessed with PCBs for builds from here, plus I enjoy this DAC almost every day. So I want to give these away/ I'll post anywhere in the world for free (untracked), but would ask that you do a 5e donation (about the cost of postage) to diyaudio given we all get some much from here.

Early birds get the worm!!
4 sets left.... will take people in the order they send a pm.
Some people need to get back to me with their postal address....
For any new builders, @Paddy Garcia is the man for AD1862 chips.
