siting in my car thinking what the answer of this would be....If I have -14 of bias voltage in an amp that has a built in bias voltage indicator and a separate bias current indicator, and need to adjust/tweak (because it is always off) the indicated bias voltage with out effecting indicated bias current, I was thinking I could do this by putting a diode in series with the bias voltage meter. this would change the bias voltage by the forward voltage drop of the diode ( about .5 to .7 volts) with out changing values to the indicated bias current meter . so the question, if I start with -14 volts and assume I have a diode with a .7 voltage drop, will the indicated bias meter voltage change to -13.3 or does it become -14.7. I'm thinking it will become -13.3 volts which is what i need it to do. I do not think it would increase the negative voltage to -14.7 since no increase in potential is actually happening. does this make sense?
