[sdiy] newbie with some questions

[John L Marshall]

RE: [sdiy] newbie with some questionsCurrent change in one module will be seen in the power leads of all modules. Think of the power leads as tiny resistors in series. The resistors share current going to the modules and therefore the changes in current. Symptoms; oscillators that sync when they are not supposed to, spurious oscillations, instability.

  I'm curious why?  The Paia 9700 is setup that way.  What's the difference between 

  V-------+-------+ 
          |       | 
          M1      M2 

  and 

  V---+-------M1 
  | 
  +-----------M2 

  ??? (Sorry for the ASCII art :-) 
  Same voltage level reaches both, right?  Thanks
