Hi,

yes I used the right sheets for 9V and for 5V (latest files newly downloade)

R4 10k
R5 12k
= 8.947 V

Add R6 820k
= 9.006 V

Try this.

Hi,

after adding R5 12K and R6 820K i get exactly 9,06 V  :-D :-D :-D
Thnk you.
For my 5V board I get 4,91 V out. How would I ge closer to 5V?

It has no importance of having exactly 5 volts but it may feel better. Can you tell me what you have as R4, R5 and R6? Measure also the voltage across R5. I'll calculate this for you.

Hi,

as per your .xls file there a no R5 or R6 only jumper for R4.

Alt 2:
27k in parallel over R9, mount at solderside.
