Not happy with how my preliminary Szekeres builds are turning out, I'm turning to the Apheared 47 as my next option for a balanced build.
As the whole point of this project is to see how much you can do on a budget, my cheapskate solution for a balanced volume control involves using parallel stereo alps faders (which you can get for as low as $7.0 ea.). Much easier to manipulate than two rotary knobs, and way cheaper than a quad-pot.
Apheared's design calls for a 10k pot, but the output on this circuit is apparently extremely loud, and for maximum effectiveness I need to get the most throw I can out of the faders. I'm thinking 20k pots might accomplish this, but I don't want to go off the deep end and not get enough volume out of the circuit, either.
How do I go about calculating output given different input pot impedances?
EDIT-Sorry about my spelling on my thread title. Yes that should be "calculating". Not enough coffee this morning.
