Hello all,

Let's say I have two mono sources that will be outputted as a stereo
signal to a headphone. If the mono sources pass thru two simple opamp
configured as inverting amplifiers, how do I control the amplitude
level of both mono sources simultaneoulsy? Is there a potentiometer
that has multiple variable resistors that can be controlled by one
knob?

Thanks!

dual ganged logarithmic potentiometers are made for just this purpose.
Surprising you haven't heard of them.

Radio Shack do a 100k one for $3.99 if you are in the USA


although remember that radio shack always adds there 1000% gratuity tax,
1000% feed the radio shack CEO's tax, 1000% misc tax, 1000% accidential tax,
etc...
