Keep the current mix written down as a reference since it seems OK in your application so you can have a fallback mode. How is drift as you are without a trimmer?

Yes good idea!! Voltage drift after 1 hour was non existant!! was a solid 5.4v throughout

There will be some minus drift in some applications with larger voltages and currents for mainly resistive means of Vref if preferred. I got -0.1V in 30mins in my 15V prototype with 2 leds and a Bourns trimmer. Which I trimmed up for when hot.

Wich one 10mF 80V? 35mm diameter to fit in the boards it's a little bit difficult but did you do? all questions is because I need to buy capacitors for the regs.

would it be possible to tweak in any way the negative to use as a positive (ie: reverse board and/or parts)

The BHC was not on the PCB but on a perf test. 63V it was.
