To member "Sonny"....you PM'd me but I cannt reply as your post box is full....
So I'll post here and hope you notice as it was wrt to this thread.....
Sorry for the late response...I've been in hospital for last 6 weeks...yet another spinal fusion (I've had quite a few lumber and cervical). This one worked very well but I've been spending some times on drugs and on the net...a dangerous combination.....
Anyway as for the PCB ver...I think I posted pics but am looking for them...or I'll tear it apart when I can.
Pot I used was 2K , 785-9828 RS mrn.
785-9828 Its a 3296Z Bourns pot, 2K 10% +/-100PPM/C, so yeah could have done better here! I think it was what I could get at the time!. Another Problem is its centre legs is offset so I had a bit of bending to do prior to fitting...
I'll do pics soon ummm it didn't have pads to vref IC!
Oh yeah its kept cal ever since changing the pot!

edit:
Jeez Sonny your postbox is still full....I cannot PM back to you till ya empty !
And correct pot should have been Bourns 3296x pot as these pins are inline pins and its side adjust or 3296W for a top adj pot. I'm sure top adj will fit ok. The RS 3296X pot is RS number: 521-9912, mfgr mrn: 3296X-1-202LF, RS cost $4.30 ea.
