I wanted to double check to see if I am reading this correctly. The way the pot is connected:
the output of the first op-amp connects to the inverting input of the second op amp through 10k resistance. Call this R1.
The pot varies the resistance seen from the inverting input of the second op amp to the 8 ohm speaker. Call this Rvariable.
If these connections are correct, how does Rvariable vary from the 10k. Is it from 10k down to ~ 0 ohms?
Thanks!
