I can't post pictures, so graphically I imagine the position of the parts in my question on the board to look like this, where polarity is marked by ():
6.8k | | - R220 --- R220 - | ---| |--- | | - 0.1uf ------------ | | | (+) (-) 20uf 20uf | | | | (-) (+) | |
does this make sense? Is this correct?
Also, I'm asking about the meter since resistors in series give a resistance that is the sum of the values of the resistor. If the original part is R150 and the meter resistance is the equivalent of R1 does it make sense to try to replace the resistor with roughly R149 or is R150+R1 close enough in this application? To me this is close enough, but I'm not sure. The discussion in the other thread is about a meter with a much higher resistance.
Lastly, my question about the location of the meter is not about how to build the amp, but about how the meter functions to measure the voltage drop while located between the R150 resistor and ground. I think what I'm missing in this question is how to think about voltage drop in this location, because my first inclination would be to put the meter in parallel with the resistor and not in series.
Thanks again,
