I'm sure this has probably been covered somewhere, but I can't find the answer(s).
I'm trying to understand how to adjust the 3 trimmer pots. R5(5K ohms)--adjust until you read 5V at TP? R9(1M ohms)--adjust for lowest offset at the output? Is this done with the input shorted or does it matter? R1(100 ohms)--how do you adjust this trimmer? Thank you! |

Have you looked at the schematic in the link in my signature?

Yes I have, but I still don't understand how to adjust R1.
Edit--I reread the trimming part again on your site. Is R1 for adjusting for lowest THD only? Above that it states 2:"R1=R2". That would indicate to me to adjust it to the same value as R2(56 ohms). Why not just use another 56 ohm resistor for R1 and call it a day if that's the case? Last edited by ammel68; 25th October 2015 at 04:48 AM. |

If you don't have a THD meter, R1=R2 is probably the best you can do, don't worry about it. Those who can test THD down to 0.0001% can find the best value for R1 however.
