1.02meg from 1/2v = 1/4 in Dist +'s

[petemoore]

  Just looking at my V divider of 2 x 47k strung across -/+.
  My measurement from ground to divider junction indicates 4.42v from Gnd. the, battery measures 8.94v.
  Connecting a 1m resistor to that brings it to about 1/4 supply voltage, or 2.02v.
  This Is a new board I built yesterday, and have been debugging ever since I shelved the Dist+ with the LM386 Vdivider.
  The 'LM386 supplied' Dist+ also has 2.02v shown on opamp pin 3.
  I bought some more lm741's. the readings from one opamp to the next vary only slightly.
  I added a 470k to the 1meg, in paralled this brings the voltage up to 3.3v, still not optimally biased.
  I don't believe it but expect you to, I'm only showing the exact experiment repeated, repeated earlier experiments with many DIST+'s and the "LM386 Supplied" one that decided to exhibit the odd behavior.
  I posted earlier the voltages, they are all quite nice enough for govt. work, ~1/2v are at the opamps _input and output, Gnd. is 0v at pin4, pin7 is V+
1
2  2.02v
3  4.24v
4   0v
5
6  4.36v
7  8.94.

  Everything is connected correcly except my spelling on correctly,  two builds in a row prove this wrong.
  Why do 1megs directly from, and only from 1/2v  convert to  1/4v ?

It's likely that your measurement meter is loading down the voltage through the 1K.

It is common for this to be a problem.

  I'm not sure I understand, the DIST+ has no 1k.
  This would be the first for not being able to use voltage measurements of OA pins to debug, also the circuit isn't functioning.

[R.G.]

Sorry - I meant the 1M bias resistor.

[petemoore]

  This is strange sound to me, I remember being able to bias [IIRC] Dist+'s and read the voltages on the pins.
  And it seems this pin is where the signal isn't 'going in', as there is no 'click' on pin 3, pin 2 has an 'amplified a little' click, and the output has a click similar to farther toward output of the circuit/the amps plug tip.
  So although I can understand how a 1meg could 'screw' with the meter, [not how that would] and show a false reading, I'll go mess with it again and make sure if it's not working.

[petemoore]

  It is working just fine.
  I messed about for times, then tried the Ohter new Opamp, good thing I bought two, fired right up. Wierd as anything. I guess my little DMM doesn't like reading voltages through big resistors, otherwise the opamp sounds biased, I guess you Cant always trust the DMM.
  A slight increase to .022uf input cap, also 1uf [instead of 10] output, seemed bassy enough, .1uf though 'starved' it a bit.
