I've never used the trimpots for adjusting the voltages (I usually use either matched resistors using my HP bench meter, or 0.1% resistors and live with the results.) That's what I was thinking. Is there any harm leaving it as is? I'm ok with the results 6 minutes ago, mwl168 said: Judging by the photo you should definitely see output voltage change as you adjust the pots. If not, I would first check to see if the pins of the pot are soldered in correctly - is it possible you soldered pin 1 and 3 of the pots to the fixed resistor positions? I'll check it tonight, anything is possible Quote Link to comment Share on other sites More sharing options...
